9. SO WHAT IS INFRARED?
All objects emit infrared energy, at temperatures above absolute zero (-273°C, -460°F)
Sir William Herschel discovered infrared radiation by measuring the temperature of various colors separated by a prism.
Herschel accidentally placed his thermometer below the red region, and noted a further increase in temperature.
Herschel called this invisible light, infrared, which means below red.

10. Infrared Thermometry Thermopile detector measures target radiation

15. Field of View
The ratio of distance between target and sensor to the spot size.
Every sensor has a minimum spot size, and the spot size will never be smaller than the minimum spot size
We offer FOV’s from 1:2 to 100:1
Example: Distance between sensor and target = 5”, Spot size is 1” diameter, the field of view is 5:1.

20. Input Devices Incorporation the IRt/c Polynomials
QHi
Numerous OEM customers in custom controls or computer interfaces

21. LINEARIZATION TIPS The mv tables provided give the best accuracy
When input device requires polynomial, take specific data for the temperature range of interest and generate the polynomial from the data in that range only for the best accuracy
mV tables provided are good for ambient temperature of 25C
IRt/c’s are calibrated for elevated ambient based on model and calibration point
Even with linearization the ambient compensation works best when using model closest to the calibration point.
After linearizing the input device, offset and gain adjustments for leakage current, ambient shifts, and emissivity are required for best accuracy
Cold junction compensation in the input device is handled the same as it is for any conventional t/c

22. IRt/c Installation Install IRt/c as close as possible.
Wire connections in standard fashion. (RED is (-))
At low operating temperature, measure actual temperature with DX Series or any reliable reference.
Adjust OFFSET, ZERO, or LO CAL to match reading on the reference.
At high operating temperature, measure actual temperature with DX Series or reference.
Adjust SPAN, GAIN, or HI CAL to match reading on reference.

23. TECHNICAL TIPS
IRt/c’s have higher impedance than conventional t/c’s. Be careful when selecting input devices. They must have low leakage current or enough offset to calibrate
The IRt/c’s are only linear to match t/c’s at temperatures close to their calibration points and they are most accurate there
All are calibrated for 0.9 emissivity, the emissivity adjustment is done via the input device (via gain), not designed for low emissivity (metal) targets
Be careful not to overheat sensors (use air purge when available)
Make sure spot size is smaller than the target and the sensor is aligned on the target

24. ORDERING PRECALIBRATED IRt/c’s
*- Model type (01, 03, 3X, 5, etc)
** - thermocouple type (J, K, etc.)
*** - calibration point (80F/27C, 140F/60C, etc)
Example: IRt/c.3X-K-80F/27C

25. Adjustable IRt/c’s Self Powered

26. Installation of Adjustable IRt/c’s

27. Increase linear range of Adjustables
Set the readout device to the offset value shown in Table I.
Adjust the calibration screw on the IRt/c to the correct target temperature.
Calibration complete.

28. LoE filter minimizes reflections

29. Ordering Adjustable IRt/c’s
* - model (10A, 20A, etc.)
** - thermocouple type (J, K, etc.)
*** - HiE (non-metals), LoE (metal targets)
Example: IRt/c.10A-K-LoE

Turn Power On
Mount sensor as close to target as possible
At high operating temperature, measure actual temperature with DX Series or reference.
Adjust SPAN, GAIN, or HI CAL on input device to match reading on reference (emissivity cal)

33. TECHNICAL TIPS Ambient rating is 160 °F (70 °C)
Power Supplied can be ±10%, use 12VDC for 12V models and 24VDC for 24V models
Current models (4-20mA) can only drive 50ohm impedance
Error messages are displayed via blinking LED

34. Ordering SmartIRt/c’s
* - model (3, 5, 20, 40)
** - Power (12V or 24V)
*** - Output (05, 010, 420, 232)
**** - Temperature Range (100C, 250C, 500C, 1000C)
Example: SmartIRt/c.3-24V C
