New from Calex are the PyroEpsilon series non-contact infra-red sensors, which measure the temperature of inaccessible or moving objects and materials. They are said to measure temperatures from -20-500 degC, accurately and consistently, with a response time of 240 msec.
According to Calex, the sensors’ 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. It can be adjusted from 0.2-1.0 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.
The PyroTune module can also be used as a low cost setpoint transmitter for regulating control valves or adjusting the setpoint on a remote controller.
These compact sensors are said to be small enough to fit “almost anywhere”, whilst their rugged stainless steel housings make them ideal for applications where cleanliness and hygiene are paramount.
