Contactless optical temperature measurement

November 2015 Temperature Measurement

Demonstrating innovative market competence in the area of optical sensor technology, the Wenglor OptoTemp allows contactless temperature measurement within a range of -25 to 350°C based on infrared radiation emitted by the object, regardless of the material it is made of and state of aggregation.

The sensor measures temperature with a spectral sensitivity of 8 to 14 μm. The measured value appears on the integrated display and is also sent via the output RS-232 port. Due to its two switching and an analog output, the sensor is suited for various measuring applications, for example target versus actual value comparison and absolute measurement. The integrated laser alignment tool and teachable emission factor make initial start-up quick and easy.

Applications range from conventional target versus actual value monitoring of liquids and raw masses, as well as process control for the prevention of temperature violations at non-metallic surfaces, right up to the monitoring of engines and system components in the automotive industry. Downtime is avoided, scrap can be reduced in production and uniform product quality can be assured throughout the entire value creation chain. Other features include:

• Freely scalable analogue output for absolute measurement.

• Emission factor adjustable from 0,1 to 1.

• Integrated laser alignment tool.

• Easy adjustment via intuitive menu and 7 segment display or wTeach2 (RS-232).
