Short description

The PyroEpsilon is a simple infrared temperature sensor with externally adjustable emissivity. The series is ideal when the target is partially reflective. The emissivity is adjusted via a 4-20mA input and can thus be continuously adjusted with an external source, such as a PLC control or a controller. The optional PyroTune emissivity controller is available for manual emissivity adjustment. If no 4-20mA input is available, the emissivity setting is reset to 0.95, making the sensor suitable for measuring non-reflective non-metallic materials (or painted metals).

Fixed Infrared Temperature Sensor with Adjustable Emissivity
Calex PyroEpsilon IR Temperature sensor PyroEpsilon series
The emissivity setting of the PyroEpsilon infrared temperature sensor is adjustable via an analogue input, so it can be controlled automatically during the process, for example by a PLC, or manually, by using the controls on the optional PPT245 indicating controller or the optional PyroTune emissivity adjuster. If the emissivity of the target changes during the process, then the PyroEpsilon is ideal.
The PyroEpsilon is also a good choice if a simple pyrometer with a 4-20 mA output is required, but you are not sure if the emissivity of the target surface is high enough for a fixed-emissivity sensor to be suitable. When no 4-20 mA input signal is present, the emissivity setting will default to 0.95. Emissivity adjustment may then be added later on if required.

  • Temperature ranges from -20°C to 500°C
  • Two-wire 4-20 mA output
  • Adjustable emissivity via continuously variable 4-20 mA input - measure a wide range of target materials
  • Choice of precision optics for large or small targets
  • Fast response with high stability
  • Stainless steel housing, sealed to IP65
  • Quick and easy installation
PyroTune emissivity adjuster PYROTUNE
The optional PyroTune emissivity adjuster provides a continuous 4-20mA current signal to the PyroEpsilon sensor. Simple push-button controls allow the emissivity setting to be adjusted. The built-in LCD display shows the emissivity or mA value.
 Protective Plastic Window Protective Windows
When fitted over the lens of the sensor, the protective plastic window in stainless steel holder provides mechanical protection and helps retain fragments of lens in case of damage.
