Non-contact temperature sensor

The PyroEpsilon series non-contact temperature sensors measure the temperature of inaccessible or moving objects and materials. They can measure temperatures from -20 to +500 °C, accurately and consistently, with a response time of 240 ms.

The sensors provide a linear 4–20 mA output representing target temperature, plus a 4–20 mA input to control the sensor’s emissivity setting.

The emissivity setting can be adjusted from 0.2 to 1.0 to cope with different target materials and can be automatically controlled using a PLC. Alternatively, the emissivity setting can be adjusted manually using the optional PyroTune module.

All sensors are fitted with germanium lenses for accurate optics. Made of polished stainless steel and sealed to IP65, the small, rugged sensors are suitable for applications where cleanliness and hygiene are critical.

A laser-sighting tool is available to assist in the sighting of the sensor.

If the sensor is required to operate in a high or low ambient temperature environment (less than 0 °C or more than 70 °C), it can be supplied with an optional water/air-cooled jacket. For dusty environments, an air-purge collar can be fitted to keep the lens clean.

PyroEpsilon sensors are RoHS compliant and conform to EN61326-1:2006 for EMC.
