Inline infrared sensors measure temperatures up to 1800degC

The Micro-Epsilon thermoMETER CT laser M3 is an infrared, inline (fixed) temperature sensor that measures at a short wavelength of 2.3um for all temperature measurements between 50 and 600degC. This sensor is claimed to have the lowest unit price of any 2-3um-wavelength sensor currently in the marketplace - typically 60 per cent of the cost of currently available sensors. For more information about the thermoMETER CT laser M3, see this page.

For higher process temperatures from 250 up to 1800degC, Micro-Epsilon's new thermoMETER CT laser M1/M2 temperature sensors can be used to measure the temperature of metals, ceramics and composites. Like the M3, the M1/M2 sensors have double-precision laser sighting, but they benefit from a 300:1 optical resolution and a minimum spot size of 0.45mm. Sensor response times are from 1ms.

The thermoMETER CT laser M1/M2 can be used in ambient temperatures up to 85degC without any cooling and there is an automatic laser switch-off at 50degC. The sensor measures at very short wavelengths (1.0-1.6um), which minimises temperature measurement errors on surfaces with either low or unknown emissivity.

A broad range of accessories and optional extras is available for the CT laser sensors to provide protection in harsh operating environments. These include air purging accessories, K or J type thermocouples outputs and a range of integrated digital communications interfaces, including Profibus DP, CAN open, USB, RS232, RS485 and Ethernet.
