Raytek Compact C-Series Infrared Sensors

This compact low cost sensor does not sacrifice accuracy or repeatability. Choose J or K thermocouple output—or voltage output if your application is susceptible to noise or requires a long cable run.

Rugged and reliable
Designed for easy integration into standard 4 wire systems, the CI’s onboard electronics are protected by a rugged NEMA 4 stainless steel housing. Compare this to the plastic housings used on other small IR sensors.

Thermal shock and temperature coefficient specifications are also outstanding for a sensor this small. And the 4:1 optics, 300mSec response time, and ±1% repeatability all help assure fast, accurate measurements.

Offset errors eliminated
Because the CI has the same 50 ohm output impedance as a thermocouple, it functions accurately, when used in conjunction with the thermocouple break protection circuitry in most controllers, displays, and transmitters.

Wide selection of accessories
A variety of mounting and protective accessories make installation easy and help assure reliable operation in high ambient temperatures and demanding industrial environments.

Compact, easy to install and accurate. All reasons the CI is ideal for both OEM and end-user applications. You won’t find a better value in a low cost IR sensor.
