Inductive proximity sensors with hazardous location ratings
May 17, 2013 By Alison Dunn
Carlo Gavazzi has enhanced its popular ICB Series Proximity Sensors: Certifications for use in hazardous environments. By Division, the sensors are rated Class I: Hazardous locations with presence of flammable gases or vapours; Division 2: Hazardous atmospheres only present under fault conditions and only for very short periods of time; and Group A, B, C and D: Groups of explosive gases (Acetylene, Hydrogen, Ethylene and Propane). By Zone, they are rated Class I: Hazardous locations with presence of flammable gases or vapours; Zone 1: Hazardous atmospheres may be present under normal operation, but only for short periods of time (intermittently); AEx d/Ex d: Flameproof devices (AEx d for USA, Ex d for Canada); and IIB+H2: Group of explosive gases (Hydrogen, Ethylene, valid also for group IIA – Propane). These sensors feature the same advanced microprocessor design and innovative AirCoreTM sensing coil, along with a robust potting process that allows users to install the sensor in heavy duty applications. There are no new part numbers involved, as the Class I, Div 2 Rating is an enhancement to the existing ICB Series.
