Intrinsically-safe ATEX-certified sensing and switching components

Variohm EuroSensor has extended its range of intrinsically-safe sensing and switching components. The new sensors suit a variety of applications across chemical, oil / gas, HVAC, food / beverage, and general engineering where ATEX-certified approval is a prerequisite.

The DPX9I and DPSXU electronic pressure switches, respectively equipped for current or voltage output from a 14 - 32VDC input, comprise an intrinsically safe and detachable measuring cell with a cable connection to the separate panel mounted evaluation electronics, which is mounted outside hazardous area.

The measuring cell is available in several nominal pressure ranges from 0 - 5 mbar up to 0 - 2000 bar with generous overload and burst pressure ratings. Silicon membrane technology is used for pressures below 500 mbar while stainless steel membrane and wetted materials are used the upper ranges to suit gases and solid media at temperatures from -40C to +100C.
