The Wahl Heat Spy Monitor R10 series compact, fixed infrared sensor is the base model in our "R" series of fixed infrared sensors. The housing is 304 stainless steel, IP65 (NEMA 4) and allows the device to operate at ambient temperatures up to 50°C without the need for additional cooling. All models are powered by 24VDC for easy communication with PLCs, temperature controllers or standard gauges.

This model has a temperature range of 0 to 500°C and an output signal of 4 – 20 mA. The 20:1 distance-to-spot ratio is perfect for measuring smaller target areas or in applications where the distance between the sensor and the measuring area is larger. Rated accuracy of ±1% of reading and fixed emissivity                                                                                                                      of 0.95 are suitable for measuring a wide range of materials.

 

Designed for quick and easy installation, with 1.5 meter cables or 3 meter cables available to meet your system requirements. The sensor includes two stainless steel locking nuts to fit into an 18mm diameter hole.
