Temperature sensor for small spaces

24th October 2019

A non-contact voltage-output infrared temperature sensor is now available in a small 30 mm x 31 mm size.

The temperature sensor is designed to fit into tight spaces and has a side-entry cable to facilitate placement. It displays the measured temperature in situ on a built-in backlit organic light-emitting diode, thus reducing the need for contact with the target surface. In addition, this aims to obviate the need for operators to return to the control room to check readings.

The compact unit features integrated measurement display and parameter controls and is designed for factory maintenance, repair and operations in smart manufacturing environments.

The sensor can be used in situations where contact probes are not applicable, such as when the target is moving or inaccessible; for example, between a wheel and the rim or hub of a disc brake.

The company states that its sensor can measure surface temperatures from 0 °C to 1 000 °C and to an accuracy of about 1.5% of reading or about 1.5 °C, whichever is greater, and repeatability of about 0.5% of reading or about 0.5 °C. Its response time is said to be 250 ms, with the promise of continuous monitoring by industrial process instrumentation by means of the direct current voltage output.

The sensor provides simultaneous voltage and alarm outputs. The voltage output can be configured as 0–5 VDC, 1–5 VDC or 0–10 VDC, with adjustable temperature range scaling configured using built-in controls on the sensor. The open-collector alarm output offers adjustable temperature threshold and hysteresis.

As supplied, the sensor is set up to measure non-reflective surfaces such as paper, plastics, rubber, wood, tarmac, food, pharmaceuticals, organic materials and painted metal. To measure the temperature of reflective solid or liquid surfaces, the user can adjust emissivity settings between 0.20 and 1.00.

The RS PRO infrared temperature sensor from RS Components is fitted as standard with a one-metre-long cable, which can be extended using terminal blocks or connectors. An optional air purge collar is available to help keep the lens clean in the presence of smoke, fumes, dust, steam or other potential contaminants.
