The new ExTemp series of intrinsically safe infrared temperature sensors from Calex Electronics is designed for use in ATEX and IECEx explosive atmospheres up to and including Zone 0 (gas) and Zone 20 (dust), in conjunction with a suitable safety barrier or isolator.
This range of pyrometers is available with a choice of pre-set temperature ranges from -20°C to +1000°C. All models have a two-wire 4 to 20 mA output that may be rescaled via the optional USB interface and software.
A choice of optics is available so that small or large targets may be measured at short or long distances.
All ExTemp sensors are supplied pre-configured for general-purpose use and may be used in many applications without the need for additional configuration. However, all models are fully configurable: the emissivity setting, averaging, peak and valley hold processing and reflected energy compensation parameters may be adjusted if required via the configuration software.
The robust stainless steel 316 housing is sealed to IP65 and is ideal for offshore applications.
The sensor is available with factory-fitted cable lengths from 5 to 25 metres, and the cable may be extended even further (subject to safety requirements) if required.
Optional accessories include mounting brackets, air purge collar and a UKAS traceable calibration certificate.
The ExTemp is ideally suited for applications in the petrochemical, pharmaceutical, food, automotive painting, and gas cylinder filling industries, among many more. The hazardous area classification is as follows: Ex II 1GD, Ex ia IIC T4 Ga (Gas), Ex ia IIIC T135°C IP65 Da (Dust)
