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.

Infrared Thermometry Thermopile detector measures target radiation Detector converts radiant energy into an electrical signal which is displayed Optics are used to measure a variety of field of views 434.5 F

Why use Infrared Sensors to measure temperature? Can measure moving objects Measures product temperature Won’t contaminate or damage product Longer lifetime Faster response time

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.

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

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

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.

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

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

Adjustable IRt/c’s Self Powered Allow end user to determine calibration point Can measure high temperatures LoE version for measuring metal targets Specialized optics available for small spots and slot spots

Installation of Adjustable IRt/c’s

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.

LoE filter minimizes reflections

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

Installing SmartIRt/c’s Connect to power supply (Red = +, Black = GND) Connect output wires (White = +, Green = REFERENCE) 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)

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
