The Raytek CM sensor provides the advantages of infrared temperature measurement in a powerful, compact, integrated sensor. Designed for easy integration, the CM 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 your application is susceptible to noise.

The CM sensor is designed to measure target temperatures ranging from -20°C to 500°C (-4°F to 932°F). The CM's 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 (160°F) without cooling.

Although small in size, the CM is loaded with advanced features. An RS232 digital interface allows the user to configure all programmable sensor variables with the powerful DataTemp Multdrop software included with each sensor. 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.

The built-in sensor health LED provides a convenient on-line indicator of the sensor's operating status and aids in troubleshooting initial sensor set up.

Raytek CM Series Infrared Temperature Sensors include a 1 meter (3.3ft) preinstalled cable, two mounting nuts and a Quick Start Guide. The CM has a threaded stainless housing, 13:1 optical resolution and the spectral response of the sensor is 8 - 14 microns.

Infrared Temperature Measurement - Technology Explained:

Raytek infrared thermometers measure temperature from a distance by detecting the amount of thermal electromagnetic radiation emitted from the object being measured. This allows users to accurately measure surface temperatures in hazardous or hard-to-reach places, or other situations in which non-contact temperature measurement is desirable. Infrared thermometer technology is useful in a wide range of applications – including industrial, laboratory, food service, fire fighting, hobby and home use.

While the technology is relatively simple, the myriad of names given to these devices can be confusing. "Laser Thermometers" makes reference to the laser that helps aim the thermometer. "IR Sensors" and "IR Thermometers" make use of a common abbreviation for "infrared". "Non-Contact Thermometers" is descriptive of the device's ability to measure temperature from a distance. "Radiation Pyrometers" is a scientific/technical term for these devices.
