Raytek CM (photo) is an integrated infrared temperature-measurement sensor with precision, high-resolution silicon optics. An RS232 digital interface allows the configuration of all programmable sensor variables via Raytek DataTemp Multidrop software. These include a 24-V-d.c. alarm output triggered by target temperature or head ambient temperature, and more. The remote configuration capability simplifies installation and troubleshooting, especially when the sensor is located in a hostile or remote location. The Raytek CM sensor is designed to measure target temperatures ranging from –20°C to 500°C. Its onboard electronics are protected by a rugged IP 65 (NEMA-4) stainless-steel housing, allowing the sensor to function in ambient temperatures to 70°C without cooling. — Raytek, Santa Cruz, Calif.
