Fixed-mount IR temperature sensor

The Raytek RAYCMLTV is a fixed-mount infrared sensor designed for non-contact temperature monitoring in industrial and process environments. It measures from -4 to 932 degrees Fahrenheit with a stated accuracy of ±1.5 percent. The unit operates on a 24V DC supply drawing 10mA and provides a 0 to 5V DC output signal. Its spectral response covers 8 to 14 micrometers.

Adjustable emissivity and fixed optics

The sensor offers an emissivity range of 0.10 to 1.10, allowing compensation for different surface materials without external filters. Optics are fixed at a spot size of 0.46 inches at a 6-inch distance, so the measurement area cannot be changed in the field. A 150ms response time supports monitoring of moderately fast thermal changes. The 3-foot-4-inch cable and 100-ohm impedance simplify wiring into existing control loops.

Installation checks for voltage.

Verify that a stable 24V DC source is available and that the 0 to 5V output matches your controller input range. Confirm the 6-inch working distance suits the mounting geometry, as the spot size is not adjustable. Ensure the ambient temperature at the sensor head stays within 32 to 160 degrees Fahrenheit. The 50-kilohm loop resistance must be compatible with the receiving instrument. Buyers needing a different spot-size-to-distance ratio or a wider ambient range should consider other models.

Questions about this item

Will the 0-5 V DC output need periodic recalibration to stay within the ±1.5 % accuracy spec?

The sensor maintains its rated ±1.5 % accuracy without a factory-mandated recalibration interval; verify locally if your quality system requires scheduled checks.

What limits continuous operation at the 932 °F measurement end of the range?

Ambient temperature must stay at or below 160 °F and the 24 V DC supply must remain stable; exceeding either can shift readings or trigger protective shutdown.

How hot does the housing get and how much power does it draw during all-day use?

The unit draws only 10 mA at 24 V DC, so self-heating is minimal; housing temperature tracks the 32–160 °F ambient range.
