Temperature Measurement


Infrared thermometer for industrial applications

July 2009 Temperature Measurement

Raytek has introduced the Raytek CM, a compact, integrated infrared no-contact thermometer intended for continuous temperature monitoring in a wide range of industrial manufacturing processes and OEM applications. This rugged, IP65 sealed, single-piece integrated sensor offers powerful features for a variety of temperature measurement requirements.

Designed for easy integration, the sensor can easily replace traditional contact probes with a J-type or K-type thermocouple output, or with a user-scaleable 0-5 volt output, if the application is susceptible to noise. The CM includes precision, high-resolution silicon optics, which provide excellent cost effective resolution.

An RS232 digital interface allows the user to configure all programmable sensor variables via the powerful Raytek DataTemp Multidrop software. These include a 24 volt DC alarm output triggered by target temperature or head ambient temperature; peak hold, valley hold or variable averaging signal processing; adjustable target emissivity settings; and adjustable window transmissivity setting.

A built-in sensor health LED provides a convenient on-line indicator of the sensor’s operating status and aids in troubleshooting sensor set up. The remote configuration capability caters for most applications, reducing installation and troubleshooting time, and streamlining data acquisition. This feature also eases troubleshooting when the sensor is located in a hostile or remote location.

Designed to measure target temperatures ranging from -20 to 500°C the onboard electronics are protected by a stainless steel housing, allowing the sensor to function in ambient temperatures up to 70°C without cooling.
