Smart IR Thermometer

The SmartIRt/c uses infrared rather than thermocouples to make temperature readings.

SMART IR THERMOMETER

In operation, an onboard microcomputer linearizes the measured signal and scales it in conjunction with scaling factors entered into a PLC to which it connects. Gain adjustments are made to calibrate for emissivity and the PLC displays the correct compensated temperature over the full range of the device. Several 4 to 20-mA output models feature 1-K loop impedance. Linear temperature ranges of 0 to 500 and 0 to 1,000°C are available. Output pins/triggers for alarm points are programmable and Labview executable software for RS-232 output models is available.
