Micro-Epsilon has launched a miniature infrared temperature sensor for the metal-processing industry that has an integrated controller and enables temperature measurements from -50 to 1,600C.

The Thermometer CSlaser has a double-sighting laser that precisely follows the infrared optical path and marks the real spot size at any distance, preventing inaccurate measurements on small objects.

The smallest spot size of 0.05mm (M2 version) is reached on the CSlaser at the crosspoint of both laser beams at 150mm.

The sensor can also be optimised for specific measurement tasks by fitting different lenses with varying focal lengths.

As the controller is now integrated within the sensor, the Thermometer CSlaser is suitable for applications in which installation space is limited – whether on a machine, product or tool.

Initially, the Thermometer CSlaser is available as an SF version (8 to 14um) with a measuring range between -50 and 975C, and optical resolution of 50: 1.

This version of the sensor is aimed at general temperature-measurement tasks.

There’s also an M-2 version (1.6um) for metal-processing applications, which measures temperatures from 385 to 1,600C and has an optical resolution of 300:1.

This version is suitable for use with ceramics, metal processing and metal oxides.

The wavelength of 1.6um reduces temperature-measurement errors on surfaces with low or unknown emissivity, or with changing emissivity during the process, which is often the case on metal surfaces.

’As well as providing an analogue two-wire interface, the Thermometer CSlaser can also send digital data via a USB interface to a PC,’ said Chris Jones, managing director at Micro-Epsilon.

’This enables both recording and evaluation of the temperature data, as well as remote programming and set up of the sensor, including alarm outputs, which is unusual to see on a two-wire temperature sensor,’ he said.

’The emissivity can also be adjusted either on the sensor itself or remotely using the software provided,’ Jones added.

The sensor can operate in ambient temperatures up to 85C without cooling, and automatic laser switch off is at 50C.

Optional cooling accessories are also available for use at higher temperatures.
