  • Page 18 Thermometer User Guide 4.3 Setting the Emissivity/Non Greyness value 4.3.1 U series thermometers In U series (i.e. single wavelength) thermometers, the emissivity value is set using switches SW2 and SW3. Refer to Fig. 8. The emissivity can be set in the range 0.10 to 1.09 in steps of 0.01. When switch SW2 is set from 1 to 9, this denotes the first figure after the decimal point of the emissivity value. e.g. for an emissivity value of '0.83', set SW2 to '8' and SW3 to'3'.

  • Page 22 Thermometer User Guide 4.6 Refitting the chassis into the thermometer cover When all internal controls have been set to suit your requirements, refit the thermometer chassis into the cover. Ensure that the gasket is fitted correctly on the inner face of the ther- mometer rear panel. Slide the chassis into the thermometer cover. Refer to Fig. 6. Use the 2.5mm Hex screwdriver to tighten the four cap- tive screws (A), a little at a time in turn until the chassis is secured fully. 4.7 Focusing the lens on the target Once a measurement location has been chosen and the thermometer in- stalled, the lens must be focused on the target area.
  • Page 23 User Guide Thermometer If the required target is not within the graticule, adjust the thermometer mounting until the target fills the graticule. NOTE A range of thermometer mounting accessories, to suit all measurement locations, is available from LAND. Turn the focus ring to bring the target into focus. To move the focus nearer to the thermometer turn the ring clockwise. To move the focus away from the thermometer turn the ring anticlockwise.
  • Page 24 Thermometer User Guide 4.8 Electrical Connections NOTE Do not connect a UNO thermometer to a Landmark processor unless it is a + model set to Processor mode. The electrical connections for the thermometer power supply, Peak picker reset and temperature output are made via the 6-way socket on the rear of the thermometer.

  • Page 26 Thermometer User Guide 4.8.2 Recommended wiring scheme To connect the thermometer, connect the 6-way cable from the thermometer as shown in Fig. 18. A description of each signal connection is given in the interconnection schedule, Fig. 19. WARNING Do not connect the thermometer output (or the command input of an analogue model) to the power supply rails (V+, V-) as this is likely to damage the thermometer.

Connect the computer to the pyrometer using the M12 to RJ45 4-pin D-coded Ethernet cable, LAND part number 816830, which is supplied. Then apply power to the UNO. 2. In your computer’s search box (bottom left of screen), type Network Connections. The Network Connections window displays details of each network to which your computer is connected. 3.
  • Page 29 User Guide Thermometer Mode Linear: Recommended. Gives a linear temperature output. Processor: Simulates a System 4 pyrometer and allows the UNO to be connected to a LAND LMG processor. Where Processor is selected, the emissivity is set via the pyrometer’s CMD IN. Range Select Celsius or Fahrenheit. The minimum and maximum measurement values are determined by the instrument’s hardware and cannot be changed. Emissivity Value between 0.200 and 1.090. Refer to emissivity tables in Section 5.
  • Page 30 Thermometer User Guide NOTE The peak picker works slightly differently in the analogue and + models. 1. The decay rate is logarithmic in the analogue models and linear in the + models. If you are replacing an analogue UNO with a +, use the Fig. 21 to choose the decay rate that most closely matches your existing unit. 2. The CMD IN hardware on the analogue models is different to that on the + instruments. The two inputs are not compatible. Analogue instrument: CMD IN requires a volt-free contact closure. + instrument: CMD in requires a voltage between 7 V and 24 V dc. If a + instrument replaces an analogue instrument using the CMD IN function, a suitable signal can be produced using the 24 V dc from the DPU-UI power supply as shown in Fig.

  • Page 32 Thermometer User Guide Emissivity tables In 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 applica- tion or the temperature of the target is outside the thermometer’s measure- ment span.

  • Page 35 User Guide Thermometer Maintenance Thermometer maintenance consists mainly of ensuring that the lens is clean. If the lens becomes dirty clean it with lens cleaning fluid and a soft cloth. If it is found that the lens is repeatedly becoming dirty, it may be necessary to use the thermometer in conjunction with the System 4 air purge (LAND Part Nº 091.561). Contact LAND for more information. If the thermometer is used in conjunction with a cooling jacket, ensure that there is an adequate supply of cooling water.

  • Page 38 Thermometer User Guide Principle of Operation Fig. 1 shows the field of view for a standard UNO Thermometer. The axis of the field of view is fixed at the centre of the thermometer lens and is at right angles to the front face of the thermometer. Fig. 2 shows the field of view for a Thermometer fitted with the Target Orbit- ing (TO) option. The target spot diameter at any given distance is identical to that of the corresponding standard Thermometer. However, the field of view rotates about a 'cone' of half-angle 2°. This 'cone' is at right angles to the front face of the thermometer. The axis of the cone passes through the cen- tre of the thermometer lens.
