Robust infrared temperature sensors

January 2015 News

The new TW industrial infrared temperature sensors from ifm electronic have been developed for non-contact temperature measurement of hot objects up to 2500°C. The sensors indicate the temperature value on a display and send it as an analog or switching signal to the controller.

To achieve maximum accuracy, users can select sensors with different spectral characteristics for different temperature ranges. The result is a sensor family optimised for the specific application.

TW sensors are designed for the precise temperature measurement of particularly hot objects or objects which are difficult to access, such as those found in the steel, plastics or glass industries. All four variants feature a high-quality precision lens – the prerequisite for precise measurement. The lens withstands harsh environments, for example in steelworks, and reduces the influence of external light.

To enable precise temperature measurement, the degree of emission can be quickly and easily set using the pushbuttons and display. The current temperature of the object to be measured is displayed during operation. Besides variants with switching and analog outputs (4-20 mA), sensors with two freely programmable switching outputs are also available.
