EEx de II CT6

(pressure proof encapsulated)

For Ex areas ≥ Zone 1, all pressure switches can be delivered in pressure-proof

encapsulated design (Ex degree of protection EEx de II CT 6).

PTB approval: Ex-90.C.1059.

EEx-ia

(intrinsically safe)

For intrinsically safe control circuits (Ex degree of protection EEx-ia), the pressure

switches can be delivered with gold contacts, proximity switches as well as with the blue

terminals and cable entries customary in the EExi area.

An isolating switching amplifier, which transfers the control commands of the pressure

switch from an instrinsically safety control circuit (EEx is IIC) into a not intrinsically safe

active circuit, is required in addition to the pressure switch.

Switching housing with switching mechanismsThe switching housings consists of high quality and seawater-resistantaluminium diecastings. Three versions are available:

Housing 200 (normal version)Plug connection to DIN 43650

Degree of protection IP 54

Setpoint setting accessible from the outside.

IP 54

Housing 300With terminal connection box

Degree of protection IP 54, on request IP 65

Setpoint setting and terminal connections accessible only after removal of the terminal

box lid.

IP 54

(IP 65)

Ex Housing 700 (EEx-d version)All pressure and differential pressure switches can be equipped with these switch

housings

and are thus approved for Ex zones ≥ 1.

Pressure monitoringin explosion-endangered areas

Pressure switches with special equipment can also be used in the

Ex area ≥ Zone 1.

The following alternatives are possible:

1. Pressure switch with pressure-proof encapsulated switchingdevice, degree of protection EEx de IIC T6The pressure switch in pressure-proof encapsulation can be used directly in the Ex

area (≥ Zone 1). Maximum switching voltage, switching capacity and ambient tempe-

rature must be taken into account and the rules for the installation in the Ex area must

be observed.

All pressure switches can be equipped with Ex switching mechanisms. Nevertheless,

special circuits as well as versions with adjustable switching differences are not possi-

ble.

2. Pressure switches in EExi versionAll pressure switch in normal version can be used in the Ex area ≥ Zone 1 if they are

incorporated in an „intrinsically safe circuit“. In principle the intrinsic safety is based on

that fact that the control circuit run in the Ex area carries only a small amount of energy

which is not able to generate ignitable sparks.

Isolating switching amplifiers, e. g. Type Ex 0 or Ex 04 must be tested by the PTB and

approved for Ex-installations.

Isolating switching amplifiers must in any event be installed outside the Ex zone.

Pressure switches which are intended for EEx-ia installations can be equipped with

blue terminals and cable entries. Because of the low voltages and currents which are

carried by the contacts of the microswitch, gold plated contacts are recommended

(additional function ZF 513).

3. Pressure switches with inductive proximity switches inaccordance with DIN 9234 (NAMUR)Instead of the mechanical microswitch, contactless proximity switches can also be

built into the pressure switches. Combination of pressure switches and proximity swit-

ches (ZF 52) and isolating switching amplifiers EX 0 is permissible for Ex zone ≥ ,

degree of protection EEx-ia. Here as well the isolating switching amplifier must be

installed outside the Ex zone.

4. Pressure switches with microswitch and series resistorfor line monitoringA combination of pressure switch with mechanical microswitch connected in series

with a .3 k series resistor (ZF 526 and ZF 527) and an isolating switching amplifier in

safety technology (Type EX 041) can also be used for Ex zone ≥ (degree of protection

EEx-ia).

The isolating switching amplifier in safety technology generates an intrinsically safe

control circuit and simultaneously monitors the supply line between the isolating swit-

ching amplifier and pressure switch for short circuit and line break. Please refer to the

chapter on pressure switches in safety technology.

5. Pneumatic pressure switchesNo electrical energy is used in these pressure switches ond no ignition sparks can

arise. A prerequisite is that compressed air with a pressure of .4 bar is available and

that the pneumatic output signal can be evaluated accordingly. Please refer to the data

sheet PN for details (please request).

These versions apply also for thermostats (with the exception of version 4)

1 MediumSteam, hot water, fuel gases, air, flue gases,

liquefied gas, liquid fuels, other media

1a Sensor materialStainless steel, non-ferrous metals, plastics (e. g. Perbunan).

Are all sensor materials resistant to the medium?

Oil- and grease-free for oxygen?

2 Type approvalIs a type approval (TÜV, DVGW, PTB, etc.) required for the

intended application?

3 FunctionMonitor, limiter, limiter with interlock (internal or external).

Pressure limiter in safety engineering?

4 Direction of actionShould the maximum pressure or the minimum pressure be

monitored? Does the pressure switch have a controller

function (e. g. pump on and off)?

5 Setting range Take the wanted setting range from the type overviews.

6 Switching diff.Only for controllers / monitors

The adjustable switching differential is important only for pressure

switches with controller function. The switching differential

(hysteresis) has no significance for limiter functions.

7 Max. permissibleoperating pressure

The maximum permissible operating pressure named in the

Special pressure switch with 2 switching pointspump protection against dry operation and closed valves

Product description and applications

The PD series are special pressure switches with 2 switching points, e. g. for pump applications. The

lower switching point protects the pump against dry operation, the upper switching point against closed

valves.

The switch will switch off,

x when the pressure falls below the lower switching point (protection against dry operation

and

x when the pressure rises above the upper switching point (protection against closed

valve operation).

VCMNegative Pressure Switch (Vacuum Switch)

The FEMA Negative Pressure Switches detect the pressure difference relative to the atmospheric pres-

sure. All data on switching pressure ranges and therefore also the scala divisions on the switch units are

to be understood as the difference in pressure between the atmospheric pressure at any one time and

the set switching pressure. The “zero” reference point on the scale of the unit corresponds to the atmos-

pheric pressure at the time.

Pressure switches “of special construction”, TÜV component

tested for steam and hot water boilers according to DIN 4751 Part 2

and TRD 604, with selfmonitoring safety sensor

The technical rules for steam boiler plants with high-pressure steam generators (TRD 604) require for

operation without supervision (BoB) the use of pressure control switches and limiting devices the relia-

bility of which has to be certified by a component test of the TÜV. The stringent requirements placed on

pressure limiting devices, that in the case of leaks or on rupture of the measuring bellows the

pressure switches must switch off to the safe side, have been fulfilled in the steam pressure

control switches (DWAM) and limiting devices (SDBAM).

The DA series have the additional safety feature of a selfmonitoring safety sensor.

The DWR series have the advantage of being more universal:

y They can also be used for gas and liquid fuel.

y The DWR control switches can be used for maximum or minimum monitoring.

Sensor “Special design” by test

with 2 million switching cycles.

The pressure limiters are equipped with a reclosing lockout for the mechanical interlocking

of the switch-off state. If the switching point set on the pressure limiter is reached, the limiter

switches off, the switch-off state is retained even if the pressure changes again. Switching

back is possible only by manual actuation of the reset button. The pressure at the sensor

must have lowered so that unlocking is possible (for maximum pressure limiters) or raised

(for minimum pressure limiters). The values for the pressure change are listed in the type

overview.

Important: In the selection of the limiter, it is necessary to differentiate strictly

whether the device is used for maximum or minimum pressure monitoring. It is not

possible to reverse the direction of action at the pressure limiter.

Maximum pressure limiterswith increased safety function

The pressure limiters with safety function offer a higher degree of safety in many respects

compared with normal pressure switches. They are therefore specially suitable for

chemical process engineering plants and in heating systems in which special attention

must be paid to safety in maximum pressure monitoring.

FD

Maximum pressure limiter for liquid gas systemsTÜV tested, with manual reset interlock

Setting range 3–16 barThe series FD pressure limiters are constructed in accordance with the special directives of liquid gas

engineering. The requirements of TRB 80 Appendix II § 2 are fulfilled. All parts of the sensor coming

into contact with the medium are stainless steel .404 and .457. Over and above the requirements of

the TRB, the pressure sensor is of self-monitoring design, i. e. in the event of rupture of the pressure

bellows, the pressure limiter switches off to the safe side. The pressure sensor thus complies with

“Special Design” as defined in VdTÜV Code of Practice “Pressure 00/”. The pressure limiters are

operated in intrinsically safe control circuits (Explosion-proof Protection EEx-ia). When the Ex 04

isolating switching amplifier and a suitable resistor combination are used in the switching device of

the pressure limiter, the control circuit is additionally monitored for circuit break and short-circuit.

Important: They only may be used in conjunction with

Ex 04 isolating switching device.

Differential Pressure Control Switchesfor liquid and gaseous media e. g. for hot/cold water, steam and gas

The FEMA differential pressure control switches are suitable for monitoring and controlling differential

pressures, flow monitoring and automatic checking of filter plants.

A double chamber system with stainless steel bellows resp. perbunan diaphragm accurately detects

the difference between the two applied pressures.The differential pressure to be monitored is infinitely

adjustable within the ranges mentioned in the summary of types. All differential pressure control swit-

ches can also be used in the negative pressure area.

HCD

Pressure switches and Differential pressureswitches DVGW-tested, for non-aggressive gas applications

The pressure switches of series HCD are suitable for neutral and non-aggressive gases. They can be

used for monitoring overpressure, vacuum as well as differential pressure. For detecting overpressure,

connection is made on the pressure side at the lower connecting piece G1/4, for detecting the vacuum

pressure at the upper connecting piece G1/8 (remove locking clamp). For detecting the diffenential pres-

sure, the high pressure is applied at the lower connecting piece (G1/4) and the low pressure at the upper

connection piece (G1/8)

The pressure switch is tested to DIN 3398 part approved by DVGW for air and fuel gases to DVGW-

standards G 260.

Pressure Transmitter in 3-wire system with 0–0 V or 4–20 mA output signalThe pressure and differential pressure transmitters of Series F... + ED 3 (with voltage output) and

F + ED 2 (with current output) are almost identical to the versions... ED 1. Either a voltage signal or

a current signal is available at the plug connection.

Particular attention is drawn to the fact that in the case of Series F ... + ED 2, the current

set the response threshold to below 2.5 mA.

E

Pressure controllers, mechanical-inductivefor liquid and gaseous media

Pressure controller, 3-wire system, with 2 parallel output signals 0–10 V and0–20 mA or 2–10 V and 4–20 mA, selectable by switch

The pressure controllers of the series E, in contrast to the pressure transmitters of series F, have a signifi-

cantly steeper characteristic and are therefore suitable for converting part ranges of overpressure,

vacuum and differential pressure into electrical output signals.They serve as proportional controllers or

actual value transmitters for the pressure-dependent control of pumps, fans, valves, filling levels etc.

The technical equipment of the pressure controllers of the series E is identical with that of the pressure

transmitters, the electronics module ED is used for both series.

The active range is set by the setting spindle (end value) and by the potentiometer (proportional range).

The scale serves as estimate for the end value of the scale.

Pressure transmitter with stainless steel sensorflush with the front for the food industry, 2-wire, 4–20 mA

The normally customary pressure mediating fluid has been dispensed with in the pressure transmitters

of the SB series and contamination of the media to be measured if the measuring membrane is

damaged can therefore be ruled out. Thus the pressure transmitter is especially suitable for the food

industry or else where aggressive media have to be monitored. The metal thin film technology

guarantees high long-term and temperature stability.

Extended media compatibility due to membrane coating – Option Ilaflon-R

To extend the area of application, the stainless steel membranes (Material No. .4542) can be provided

with a highly resistant plastic coating (Ilaflon-R) which withstands even aggressive cleaning processes.

Functions

With falling temperature the frost

protection generates a rising out-

put signal 0–0 V. If the temperature

drops further, a limiter contact

(single-pole changeover contact)

is actuated.

Maximum Selection

If the output signal of the controller

(Y signal) is looped through the

frost protection, a maximum selec-

tion of the two signals takes place. If

the Y signal from the controller is

larger than the output signal of the

frost protection, the controller deter-

mines the position of the heating

valve (normal operation). If the out-

put signal of the frost protection is

larger than the Y signal of the con-

troller (risk of frost), then the frost

protection determines the position

of the heating valve.

Self monitoring sensor

The sensor acting over the entire

length is self-monitoring, i. e. in the

case of breakage or damage of the

capillary tube, “Risk of frost” is

signaled. If the signal of the control-

ler is not looped through, then the

FTS outputs the frost control signal.

Cascades for large coils

For very large heating coils several

FTS can be used in cascade.

Temperature transmitter modulesfor switchboard installationfor PT 00 sensors

The transmitters modules for switchboard installation convert the temperature at the PT00 temperature

sensor into standardized electrical signals of 0–0V (3-wire system) or 4–20 mA (2-wire system).

To rule out measured value drift due to line resistances in the sensor supply lines, connect the sensors to

the transmitter module in 3-wire system.

LMT

Average temperature transmitterfor air ducts and mixing air coils

The LMT 30 records the average temperature over the entire length of the sensor rod. Therefore this

temperature transmitter is particularly suitable for air ducts in which temperature stratification can be

expected, e. g. in mixing chambers or directly behind an air heater.

The sensor consists of a PT 00 resistance which is effective over the entire length of 3.6 m.The average

temperature recorded by the sensor is converted into a proportional output signal of 0–0 V.

Signal SeparatorGalvanic separation of analogue transmitter signals

The analogue output signals of a transmitter can be galvanically separated from the evaluation device

using a signal separator. In this way interference which affects the transmitter signal can be suppressed

and influences from earth loops prevented.

The signal separator is absolutely essential for transmitters whose output signals have to be transmitted

over long distances and for signal lines which are exposed to strong electromagnetic radiation.

The 4-channel configuration and the limitation to voltage signals results in very good value for money.

The isolating switching amplifier must be installed outside the Ex zone.

The Ex 04 isolating switching amplifier is designed additionally in safety technology.The leads between

the isolating switching amplifier and pressure or temperature switch are monitored for wire breakage

Pressure mediators / separating membranesAccessories to pressure switches and pressure transmitters

A separating membrane or a pressure mediator is necessary if aggressive, viscous or cry-

stallizing media must be kept away from the actual pressure sensor.A pressure mediator is

also indispensable to avoid cavities if easy cleaning of the supply lines is important.

Special “Milk pipe unions” to DIN 851 are customary for pressure monitoring in the food-

stuffs industry.

Pressure mediators and evaluating devices (pressure switches, pressure transmitters,

Frost protection thermostatsfor air heating and conditioning systems

FEMA frost protection thermostats reliably monitor the temperature in hot water-heated air heaters. If the

temperature falls below the set value, the thermostat switches off. A visual or audible “frost hazar” alarm

can be switched on at the same time. A fixed stop on the setting spindle at 4 hC prevents the thermostat

from being set below the freezing point due to inexpert adjustment. If the capillary tube is damaged

or broken, the FEMA frost protection thermostats reliably switch off towards the safe side (e. g. fan off),

irrespective of the temperature at the sensor. Capillary tube holders H3 are included.

Solenoid Valves for Hot Water and Steamup to 120 hC / 180 hC · TÜV-tested to DIN 32730

FEMA piston-type solenoid valves of the LG series are particularly suitable for use as stop and

safety check valves in heating installations up to 20 hC resp. 80 hC.

The coupled (automatically servo-controlled) mode of operation does not require a minimum

differential pressure; the units can open and close perfectly even in the pressureless state and with

low differential pressures.

Solenoid Valves DN 12–25normally closed, for neutral gaseous and liquid media

This range of solenoid valves is of high quality and suitable for universal application, and is not

dependent operationally on a specific minium differential pressure; the valves operate correctly

with no pressure, at slight differential pressure, and right through to maximum pressure.They are there-

fore the valves of choice for installation in plant where differential pressures fluctuate greatly

and are not possible to determine precisely in advance. The valves are also suitable for use in

heating and cooling circuits.
