IS pressure and level components
16 February 2016
Variohm EuroSensor has extended its range of intrinsically-safe (IS) sensing and switching components with the addition of Ex-approved pressure switches, level sensors and pressure transmitters from ADZ NAGANO.
The sensors suit a variety of applications in chemical, oil & gas, HVAC, food & beverage and general engineering applications, where ATEX certified approval is necessary.
The DPX9I and DPSXU electronic pressure switches, respectively equipped for current or voltage output from a 14-32 VDC 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.
ADZ’s intrinsically safe PSX2 level sensor is available in a choice of silicon or stainless steel diaphragm technology for measuring pressure ranges from 0-0.10 bar to 0-150 bar. With explosion-proof certification for Zone 0 and Zone 1 the IP68 rated sensor suits filling level measurement in tanks, vessels, and liquid systems for ATEX approved devices. The 4-20mA output sensor can be supplied in either of plastic or stainless steel casings.
The SMX2 intrinsically safe pressure transmitter can be used in both zone 0 and zone 1 and meets the requirements of Directive 94/9/EC. A wide choice of pressure connectors and cabled or connectorised electrical interfaces ensure application flexibility.
