Micro-Epsilon has extended its range of non-contact temperature sensors to include a compact infrared ratio temperature sensor suitable for use in high-speed, high-temperature environments, including those found in metal casting, welding, forming and sintering.

The Thermometer CTratioM1 two-colour sensor measures temperatures from 700ºC up to 1,800ºC. The device can operate in ambient temperatures up to 250ºC without requiring any cooling.

The sensor is insensitive to dust, smoke fumes and steam. Using the ratiometric measuring principle, the device minimises measurement errors caused by laser intensity changes, low emissivity and partial spot size coverage. Even in cases where the infrared radiation beam is weakened to 95 per cent of its original intensity due to smoke or steam, the ratio pyrometer provides faultless, reliable measurements, according to the company.

The Thermometer CTratioM1 is said to be particularly suitable for measuring high temperatures on metals and for monitoring fast-moving production processes. It is designed for companies that need to measure the temperature of metals, metal oxides, ceramic or semiconductor materials in harsh environments.
