Infrared Temperature Sensor

M R K Engineers offers an infrared temperature sensor, Thermalent CI, which provides the advantages of infrared temperature measurement in a compact, low cost integrated sensor. Designed for easy integration into a standard 4-wire system, the device can easily replace traditional contact probes with a type J or K type thermocouple output or with a 0-5 volt output if the application is susceptible to noise or requires a longer cable run. The CI is designed to measure target temperatures ranging from 0 to 500?C. The sensor's onboard electronics are protected by a rugged NEMA-4 (IP 65) stainless steel housing and it can function in ambient temperatures to 70?C without cooling. With water cooling the CI has the same 50 ohm output impedance as a thermocouple. It functions accurately with out offset errors when used in conjunction with the thermocouple break protection circuitry in most controllers, displays and transmitters. This is very compact, easy-to-install, powered by 12-24 V DC at 20 mA with response time of 350 msec.
