Non-contact temperature sensor

The PyroEpsilon compact infrared sensors measure the temperature of inaccessible or moving objects and materials in the range of -20 to 500°C, with 240 ms response time.

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. This method of emissivity adjustment is more accurate and repeatable than a built-in potentiometer and less prone to drift through vibration.

The sensor’s emissivity setting can be adjusted from 0.2 to 1.0 to cope with different target materials and presents the opportunity for automatic control using a PLC, or manually using the optional PyroTune module.

The IP65-rated stainless steel sensors are suitable for applications where cleanliness and hygiene are paramount, and are fitted with precision Germanium lenses for accurate optics. A laser-sighting tool is to assist in the sighting of the sensor.

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