The Raytek CI model 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 CI 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.

The CI sensor is designed to measure
target temperatures ranging from 0°C to
500°C (32°F to 932°F). The CI unit'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. With water cooling,
the CI sensor can withstand ambient
temperatures to 260°C (500°F).

Because the CI unit has the same
50 Ohm output impedance as a
thermocouple, it functions 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 sensor is ideal for both OEM
and end-user applications.

D:S is the optical resolution expressed as a ratio of the distance to the resolu­tion spot divided by the diameter of the spot.

Optical resolution for the CI sensor is 4:1. Nominal spot size based on
90% energy.
