  • Page 5: General Description

    The IRTS-P is an infrared temperature sensor calibrated to output the signal for the target temperature with the same output voltage as if a Type K thermocouple were sensing the target temperature.

  • Page 6: Installation

    The IRTS-P can be mounted to a Campbell Scientific tripod or tower with the UT018 Crossarm (Figure 3-1.) A mounting kit (Stainless steel bolt, 2 washers, and 2 nuts PN 14475) is included with the IRTS-P that can be used to attach the sensor to the crossarm (Figure 3-2.) FIGURE 3-1.

  • Page 7: Wiring

    IRTS-P Precision Infrared Temperature Sensor 4. Wiring The IRTS-P has two thermocouple outputs. Each output is a pair of red and yellow wires. The pair labeled “Target” on the jacket near the wires is the output from the detector. The pair labeled “Body” is a thermocouple measuring the temperature of the sensor body.
