The Raytek CI series of non-contact infrared temperature sensors provides the advantages of infrared temperature measurement in a compact, low cost, integrated temperature sensor.

Designed for easy integration into a standard 4-wire system, the Raytek CI infrared temperature sensor can easily replace traditional contact probes with a J-type or K-type thermocouple output or with a 0-5 volt output if your application is susceptible to noise or requires a longer cable run.

These Raytek infrared temperature sensors are designed to measure target temperature ranging from 32°F to 932°F (0°C to 500°C). The Raytek CI Series' onboard electronics are protected by a rugged IP 65 (NEMA-4) stainless steel housing, allowing the sensor to function in ambient temperatures to 160°F (70°C) without cooling. With water cooling, the Raytek CI infrared temperature sensor can withstand ambient temperatures to 500°F (260°C).

Because infrared temperature sensors from the Raytek CI Series have the same 50 Ω (ohm) output impedance as a thermocouple, they function accurately - without offset errors - when used in conjunction with the thermocouple break protection circuitry in most controllers, displays, and transmitters.

Compact. Easy to install. Affordable. The Raytek CI infrared temperature sensor is ideal for both OEM and end-user applications.

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.
