ATEX II 1/2G EEx ia IIC T5,
e.g. for use at zone 0 (measuring volume), surrounding area zone 1
1080 - 1 mbar (hPa)

DVR 4/DVR 4S are fully electronic vacuum gauges with ATEX certification for use in areas with potentially explosive atmospheres (measuring volume: ATEX category 1, e.g. for zone 0). They have an integrated transducer made of alumina ceramic with excellent long-term stability and high permissible gas temperature. Their independence from mains power supply, ease of use and combined large digital/analogue display for quick trend detection and precise readout make these instruments very versatile. The DVR 4S features an additional current-loop interface (4 - 20 mA) for remote pressure readout. They are mechanically robust, free of mercury and cadmium, without fragile mechanical components, for use in chemical and process industries, plant and process technology.
