Fixed IR sensor for process monitoring

The Raytek RAYCI3B10L is a fixed-mount infrared temperature sensor designed for continuous process monitoring. It provides non-contact measurement with a 4:1 distance-to-spot ratio and a fixed emissivity of .95. The unit operates from 212 to 932 degrees Fahrenheit and connects via a 10 ft cable with 50 ohm impedance.

Verify mounting thread and temperature range

Before ordering confirm that your equipment has a 3/4"-16 UNF2A threaded port for installation. Ensure the process temperature stays within the 212 to 932 degrees Fahrenheit measurement window. The sensor carries an IP65 rating and NEMA 4 enclosure rating for dust and water ingress protection in industrial environments.

Replaces contact probes in high-heat zones

This sensor upgrades from thermocouples or RTDs where physical contact is impractical or sensor wear is excessive. The jump is worth it when measuring moving surfaces, electrically live parts or temperatures above the limits of wired probes. It is not suited for applications requiring adjustable emissivity or a wider distance-to-spot ratio.

Questions about this item

Does the Raytek RAYCI3B10L include a power supply or display unit, or must those be purchased separately?

The sensor ships with a 10 ft cable and UNF2A 3/4"-16 mounting thread; a separate power source and readout device are required for operation.

Should I choose a different distance-to-spot ratio or emissivity range for my application?

This model has a fixed 4:1 distance-to-spot ratio and fixed emissivity of 0.95; other ratios or adjustable emissivity would require a different sensor.

What does the 932 °F maximum temperature mean when the sensor is installed in a machine?

It indicates the highest surface temperature the sensor can measure; the unit itself is rated to operate up to that same 932 °F limit.
