Contactless intrinsically safe (Exi) infrared temperature sensors. The ExTemp’s IIC T4, IIIC T135°C, ATEX and IECEx rating makes it suitable for many applications in hazardous areas, including: Petrochemical – condition monitoring, Petrochemical – liquid storage and processing, Paper, Coal conveyors, Gas cylinder filling, Automotive painting or Offshore.

A choice of optional adapters is available to allow configuration of the ExTemp sensor. Both adapters must be connected on the safe side of an Intrinsically Safe barrier or isolator. The barrier or isolator must be capable of digital communications over 4-20 mA, and correct loop polarity must be observed. Configurable settings include the emissivity setting, 4-20 mA temperature range, averaging, peak and valley hold processing and reflected energy compensation.
