Non-contact temperature sensor

The PyroEpsilon series is a range of high-quality, low-cost, compact sensors which 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.

PyroEpsilon 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 far more accurate and repeatable than a built-in potentiometer, much easier to access 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. Alternatively, the emissivity setting can be adjusted manually using the optional PyroTune module. If the 4-20 mA input is left open or short circuit the emissivity setting defaults to 0.95.

All PyroEpsilon sensors are fitted with precision Germanium lenses for accurate optics.

These compact sensors, made of polished stainless steel and sealed to IP65, are small enough to fit almost anywhere and their rugged stainless steel housings make them suitable for applications where cleanliness and hygiene are paramount. A laser-sighting tool is available to assist in the sighting of the sensor.

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