  • Page 8 series Fixed Spot Thermometer Notes for IQR Thermometers • IQR ratio thermometers have an internal heater that must be warmed up before valid temperature readings can be produced. This can take typically 2 to 3 minutes at room temperature, followed by a further stabilisation time of 2 to 3 minutes before a fully reliable reading is available. • During the warming up period, the instrument will indicate ‘Obscuration’ and the temperature output is either held under range or over range, depending on your chosen setting for upscale/downscale drive under conditions of signal obscuration. • At ambient temperatures of 50 °C or above, the instrument will produce a valid output immediately, but will still require 2 to 3 minutes settling time. • In a cold environment, at the lower end of the ambient operating temperature range, the warm up time required may be in excess of 10 minutes at the nominal 24 V power supply voltage. A longer period may be required if the power supply voltage is below the nominal value. If your application process is not continuous (e.g. switched off overnight), or if it is in a cold environment, it is recommended that any IQR installation has a continuous power supply. This is especially relevant if your process needs to be restarted quickly. 2 - 2 User Guide...

    series Fixed Spot Thermometer HARDWARE CONFIGURATION IQ Series thermometers offer simple analogue ‘plug & play’ and digital methods of communication. 3.1 Thermometer configuration 3.1.1 Principal Features All IQ models include laser sighting to denote the centre of the measurement area. Activating the laser can be done using either the push-button mounted on the top of the connection PCB or by an external volt free contact closure across the LSRin and Com terminals on the connection PCB. Once activated the laser will remain illuminated for a period of 120 seconds. They also have RS485 digital communications, signal processing, 2 x relay alarms and include PC configuration software which is used to configure all of the above. See IQ series Windows Configuration Software User Guide for more details (part number 806230). Fixed, color-coded spacers allow the user to set the focus distance as they wish to any of the four pre-defined available distances. Note: Changing the focus distance does not affect instrument calibration. User Guide 3 - 1...

  • Page 10: Laser Alignment

    series Fixed Spot Thermometer LASER ALIGNMENT Warning CLASS 2 Laser Product. DO NOT stare into laser beam (1.0 mW maximum output at 650 nm). DO NOT look directly towards the thermometer window, or into the laser beam during operation. If the laser is projected onto a highly reflective surface, DO NOT look at the laser stripe from a position where a direct (‘mirror- like’) reflection may enter the eye. Warning CLASS 2 Laser Product. DO NOT attempt to disassemble the laser unit or any of its mounting components. IQ Series thermometers are fitted with a laser alignment utility, which can be used to align the thermometer accurately on the required target. When the laser is activated, a laser beam is emitted from the lens in the front of the IQ Series thermometer. The laser beam defines the centre line of the thermometer field of view. For details of the target size at a particular point in the field of view, refer to the target size table for your thermometer. 4 - 1 User Guide...
  • Page 11 series Fixed Spot Thermometer There are four methods of activating the laser alignment utility in the IQ Series thermometer: • the laser switch on the rear face of the thermometer (See Fig. 4-1); • a direct connection between pin Com and LSRin on the electrical connector on the rear face of the thermometer. This connection can be made via a user-supplied external switch; • The laser ‘button’ in the configurator software. Refer to Section 5.2; • By sending an appropriate message to the thermometer over an RS485 digital communications link. When the laser is activated, it will remain switched on for 2 minutes (120 seconds). Warning CLASS 2 Laser Product. If the lens is removed for re-focusing the thermometer, the laser energy emitted is increased. Therefore, ensure that the laser is switched off before re-focusing the thermometer Laser beam Laser warning labels Fig. 4-1 Location of laser warning labels on the IQ Series Thermometer User Guide...

  • Page 24: Recommended Installation Arrangement

    series Fixed Spot Thermometer 6.1 Recommended Installation Arrangement The location of the IQ thermometer should be carefully chosen, such that it is easily accessible and in a position not unnecessarily exposed to heat, fumes or liquid spray. The sight path between the IQ thermometer and the target, should be as free as possible from smoke, liquid spray and from the intrusion of machinery. The axis of the thermometer should be at right angles to the target surface, however, an angle of up to 45° from the normal is acceptable. If the thermometer to be installed is a monochromatic or single wavelength variant (SN1 etc), it must be positioned such that at the chosen target distance, the field of view of the thermometer is completely filled. The target size required to fill the field of view can easily be determined, according to the lens configuration and the distance of the thermometer from the target (see ‘IQ Thermometer Sighting’). IQ Thermometer Installation 1. Choose a suitable location for mounting the thermometer. The following criteria should be considered when making the choice: • If the installation area is not clean or free from dust, smoke or water spray, then a Land air purge system must be utilised to ensure that the thermometer lens is kept free from such airborne contaminants. Ensure that a suitably conditioned air supply is available. • If the surrounding ambient temperatures of the installation area are outside the thermometer specification, then a Land air or water cooled protective jacket must be utilised to ensure that the thermometer operates at the specified ambient temperature. Ensure that a suitably conditioned air or water supply is available. 2. Position and mount any required thermometer mountings and/or accessories. 3.

  • Page 26: Using The Brainboxes Usb/Rs485 Convertor

    series Fixed Spot Thermometer Four terminals are provided for the thermometer onboard RS485 communications. Connection to these terminals by a PC with an RS485 port enables use of the bundled IQ series configuration software. From the software interface, many more configuration parameters are available. Refer Section 5.1 of this User Guide, or to the IQ Windows Configuration Software User Guide for more details. The RS485 terminals also allow the customer to communicate digitally with the thermometer using a plant computer/PLC, PC (using Hyperterminal or similar) or any other RS485 enabled capable device. Using the thermometer in this manner allows the user to connect multiple thermometers to a shared RS485 bus. Each thermometer can be allocated a unique address (by separately configuring the thermometer using the IQ series configuration software or Hyperterminal) so the plant computer can identify which thermometer to read/write data from/to. The RS485 communication protocol is published in Appendix A of this User Guide. The second terminal strip also allows connection to two alarm relays. The relays are fully configurable from within the IQ series configuration software or over the RS485 digital communications. 6.3 Using the Brainboxes USB/RS485 convertor For configuring the IQ digital models, you can use an RS485 connection and the IQ setup software. In 4-wire transmission (full duplex RS485), 4 wires run from TXD or RXD on the master to the opposite (TXD or RXD) on the slave(s). Fig. 6-2 6 - 4 User Guide...

The averager response can be adjusted to suit the application. With a fast response speed, the temperature output signal tracks the input signal closely, any rapid fluctuations in the input are reflected in the output. With a slow response speed, the temperature output signal is much smoother, displaying more the ‘trend’ of the input signal rather than rapid changes. User Guide 7 - 1...

  • Page 30: Peak Picker

    series Fixed Spot Thermometer 7.2 Peak Picker The Peak Picker function can be used to monitor the highest temperature measured by the thermometer. This feature is useful especially for moving targets and/or where the target is obscured partially by moving machinery. The Peak Picker time function utilises the following features: Mode - In ‘Reset’ mode, at the end of the ‘OFF’ delay the temperature output signal falls to ‘under-range’, until the temperature input next rises above the threshold level. In ‘Hold’ mode, at the end of the ‘OFF’ delay the temperature output value is held constant until the temperature input next rises above the threshold level. Threshold - Temperature above which the Peak Picker is active, used in conjunction with the ON and OFF delay. (Tmin° to Tmax°) Decay Rate - A user-adjustable value at which the stored temperature output signal decays. ON Delay - Time period between the temperature rising above the threshold level and the peak picker function switching on.

Thermometer Default Emissivity/Non Greyness 0.82 0.86 0.97 It is also possible to set the emissivity/non greyness digitally. This is done using either the bundled IQ series configuration software or using an appropriate RS485 enabled device sending the thermometer the correct digital messages (see Appendix A – RS485 communication protocol). To obtain accurate temperature measurements, the emissivity value of the target surface must be known. This section of the User Guide contains typical emissivity values of the most commonly measured materials for each thermometer variant. 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 AMETEK Land Instruments International. 8 - 2 User Guide...

    Fixed Spot Thermometer MAINTENANCE, SERVICING & CALIBRATION IQ Series thermometers do not have any user serviceable parts and therefore require minimal maintenance to ensure trouble-free operation. 9.1 Maintenance Although IQ Series thermometers require no regular maintenance programme, it is essential that they are kept clean and free from contaminants at all times. Particular attention must be given to lens cleanliness in order to ensure accurate thermometer operation. To promote good working practice, it is also recommended that thermometer cleanliness and service integrity checks should be added to any local plant maintenance schedule. 9.2 Servicing IQ Series thermometers do not incorporate user serviceable parts, therefore in the unlikely event of an instrument malfunction, or an instrument requiring servicing or calibration, contact AMETEK Land Instruments International for information regarding the ‘return to manufacturer’ policy. 9.3 Calibration IQ Series thermometers are inherently stable with time. However, in line with any local quality assurance procedures, it is highly recommended that they are calibration checked every 12 months. This ensures that the instrument operates with accuracy and reliability. User Guide 9 - 1...

  • Page 47 series Fixed Spot Thermometer USER CALIBRATION CAUTION If the user calibration is adjusted away from its default value of 1000, the factory calibration will be no longer valid. However, returning the value to 1000 will restore the factory calibration. What is it for? IQ Series thermometers are factory calibrated against source temperatures that are traceable to international standards. Therefore, the user calibration should not normally need to be adjusted from its default setting of 1000. However, some users may choose to use the user calibration facility – perhaps to match the instrument to a locally maintained temperature standard, or to compensate for energy loss through a viewing window. What does it do? Single wavelength thermometers detect incident radiation and convert this detected radiation into a signal that is proportional to the incident power or brightness. The user calibration is applied as a factor to this brightness signal. The nominal setting of 1000 equates to a factor of 1 (the user setting is divided by 1000) – giving no correction to the brightness. User Calibratio Corrected Brightness ∗ Brightness 1000 Brightness is non-linear with temperature, so to produce a final temperature a linearization function must be applied. Indicated Temperatur Corrected...
  • Page 48 series Fixed Spot Thermometer %/C tables for SOLOnet thermometers are provided at the end of this Appendix. Determine what temperature correction you would like to apply – ∆T (ensure that you start with user calibration = 1000) Look up the thermometer %/C sensitivity (S) in the appropriate table – linearly interpolating between values if required. Calculate the required User_Calibration: User_Calibration = 1000 + Θ *S *∆T Example IQ1 reads 1002 °C. User wants it to read 1000 °C, so ∆T= -2 °C From the IQ1 %/C table, S = 0.93 @ 1000 °C So... User_Calibration = 1000 + Θ *0.93 *(-2) = 981 Practical Method Whilst in the user configuration screen, adjust and apply new user_calibration values until displayed temperature matches desired value Window Correction Normally the window transmission (T) will be known. In this case its effect can be corrected by 1000 User Calibratio Where T is the fractional transmission (1 = perfect transmission) Window transmission = 0.9 1000 User Calibratio 1111 Note that this calculation assumes that window reflections contribute negligible radiant energy compared to the target. This is generally true for high temperature thermometry. At low temperatures (e.g. room temperature...
