3.1 Positioning the Optic HeadIfyourUNOFibropticthermometerisfittedwithaLaserAlignmentUnit(e.g. U1 600/1600 C Y L), the laser be used to aid the installation of the thermometeropticheadbydefiningthetargetareaonwhichtheopticheadis aligned. This is particularly useful in applications where the target size is small and/or where correct alignment is critical. For more information on the Laser Alignment Unit, refer to Section 5.

In many cases, there are few options on location of the optic head, as this is generally dictated by the particular measurement application. Observe the following precautions:

1) Ifyourthermometerisan'U'seriesthermometer(e.g.U1600/1600CL), it must be positioned such that, at the chosen target distance, the targetislargeenoughtocompletelyfilltheoptichead'sfieldofview.Refertothetargetsizetables,Section5.Thethermometer'sviewofthetarget area must not be obstructed.

2) Ensurethattheanglebetweentheoptichead'slineofsightandthetarget area is as near to 90° as possible. However, if this is not possible, a viewing angle of up to 45° is acceptable.

3) If the optic head is located in an atmosphere containing a high proportion of dust/smoke etc, an air purge must be used in conjunction with the optic head. This prevents the lens from becoming dirty. Refer to the Installation Guide supplied with the mounting/purge assembly.

3.1.1 Installing the optic headThe optic head can either be mounted directly into a threaded hole in a user-supplied mounting plate, or connected to one of the range of Land Fibroptic thermometermountingsbymeansofthe'QuickReleaseFitting',LandPartNº029.591.

To mount the optic head in a plate:

1) Refer to Fig. 4(a). Unscrew the clamp nut nearest the lens on the optic head.

2) Screw the optic head into an M22 x 1.5P threaded hole in the plate.3) Re-attach the clamp nut onto the optic head. Tighten the nut so that the

mounting plate is held securely between the two clamp nuts on the optic head.

To mount the optic head into Land Fibroptic thermometer mountings:

1) Refer to Fig. 4(b). Screw the two clamp nuts up as far as they will go on the thread on the optic head.

2) Screwtheopticheadintothe‘QuickReleaseFitting’.3) Attachthefitting,plustheoptichead,totheLandFibropticthermometer

mountingbymeansofthetwistlockontheQuickReleaseFitting.


3.2 Installing the lightguideWheninstallingthefibreopticlightguide,observethefollowingprecautions;

1) Ensure that the lightguide is not be subjected to any tension or other undue force. It is not necessary to clamp or lash the lightguide to surrounding structures unless, by leaving it hanging, it will vibrate violently, be a nuisance or a hazard.

2) Treat the lightguide as if it were a lightweight electrical cable and protect it if necessary. The minimum bend radius is 50mm.

3.3 Positioning the ThermometerWhen choosing a location for the thermometer, observe the following precautions:

1) If the thermometer is to be installed in a location where the ambient temperatureisoutsidetherangespecifiedforthethermometer,itmustbe mounted in a special cooling/heating jacket available from Land Instruments International.

2) If the thermometer is to be used in conjunction with a protection jacket, refer to the installation guide provided with the jacket.

3) If the thermometer is to be installed in a location where the ambient temperatureiswithintherangespecifiedforthethermometer,itcanbemounted using the two tapped holes on the mounting pad. Either hole can be used for direct tripod mounting.

4) Choose a location for the thermometer which is free from excess vibration, dirt and moisture.

5) It is important that, in order to prevent any possibility of water ingress into the electronics/detector module, the thermometer is mounted in the orientation shown in Fig. 3.

6) It is recommended that, in order to minimise the build-up of dirt etc. on the electrical and lightguide connectors, the thermometer is mounted such that these connectors are on the underside (as shown in Fig. 3).


4 Using the ThermometerBeforefinalinstallationofthethermometer,theinternalcontrols(i.e.Emissivity, Averager response speed or Peak picker decay rate) must be set to match the particular measurement location. This involves removing the internal chassis from the thermometer cover.

4.1 Removing the chassis from the thermometer cover

4.7.2 Recommended wiring schemeIt is recommended that the UNO thermometer is used in conjunction with the Land DIN Power supply Unit (DPU). In addition to providing the correct power supply voltage for the thermometer, the DPU has simple connections for mains supply, temperature output signal and Peak picker reset command signal.

To connect the thermometer to the DPU, connect the 6-way cable from the thermometer across pins 1 to 7 of the DPU as shown in Fig. 16. A description of each signal connection is given in the interconnection schedule, Fig. 17.

5 Laser Alignment Unit

5.1 About the Laser Alignment UnitThe Laser Alignment Unit for Land UNO Fibroptic Thermometers is designed to aidtheinstallationofthethermometeropticheadbydefiningthetargetareaon which the optic head is aligned. This is particularly useful in applications where the target size is small and/or where correct alignment is critical.

TheLaserAlignmentUnitmayalsobeusedforfindingthecorrectdistancefrom the target at which to mount the optic head, as the laser image is sharpest at this point. This distance may not necessarily be the nominal focal distance.

IfyouhaveathermometerfittedwithanA10optichead,thelaserimageprojected by the alignment unit will be an almost full bright spot. For A25 and A50 optic heads, the laser image will consist of many individual bright lightspots,spacedrandomlywithinthefieldofview.

5.3 Using the Laser Alignment Unit

Warning

Class 1 Laser Product. This laser product does not permit human access to laser radiation in excess of the accessible emission limits of Class 1 for applicable wavelengths and emission durations. Refer to BS EN 60825-1, 1994.Embedded laser (diode) is Class 1M, <5mW. Do not view directlywithopticalmagnifiers.

Caution

Use of controls or adjustments, or performance of procedures otherthanthosespecifiedhereinmayresultinhazardousradiation exposure.

1) Choose a measurement location for the Optic Head (Refer to the Installation Guide and Section 2.1 of this User Guide).

2) Connect the Thermometer to a suitable power supply. WhentheThermometerisfirstswitchedon,theLaserAlignmentUnit

is activated and the target spot is illuminated by red laser light. When the laser is activated, a red LED in the push button on the front of the thermometerflashesforthedurationofthelaser(115seconds).

3) If the Laser Alignment Unit switches off before the optic head is aligned, press the button on the front of the Thermometer. Refer to Fig. 19.

4) Adjust the mounting of the optic head so that the required target is in thefieldofview(i.e.illuminatedbythelaser).Notethatfor'U'seriesUNOFibropticThermometers,thetargetmustfillthefieldofviewcompletely.

5) When the alignment of the optic head is correct, secure the mountings and tighten the optic head lock nuts.

5.4 Laser Alignment Unit maintenanceThe Laser Alignment Unit will operate reliably for years, provided it is operatedwithintheambienttemperaturesgiveninthespecification(RefertoSection 5.2).

If the Laser Alignment Unit develops a fault, return the Thermometer to Land Infrared.

7 Emissivity tablesIn order to obtain accurate temperature measurements, the emissivity value of the target surface must be known. This section of the Thermometer User Guide contains emissivity values of the most commonly measured materials for each UNO thermometer. Where no emissivity value is quoted, this means that either the thermometer is not suitable for the measurement application or the temperature of the target is outside the thermometer’s measurement span. If you have a query regarding the emissivity of the target in your measurement application, contact Land Instruments International.
