All Pressure Stations Now ATEX Approved

The three pressure generating stations available for the DPI 620 advanced multifunction calibrator from GE Sensing & Inspection Technologies (UK) are now ATEX approved for stand-alone operation in hazardous areas. These high performance pressure generators can be used instead of conventional hand pumps and inconvenient gas bottles to provide greater efficiency, better ease of use and improved safety. When combined with a reference instrument such as GE’s intrinsically safe Druck DPI 104, they will find application in gauge comparison and pressure calibration throughout the industrial and process sectors.

The PV 62x series of pressure stations comprises three models. The PV 621 features a conventional hand pump, volume adjuster and pressure/vacuum selector and will generate pneumatic pressures of up to 20 bar (300 psi) with little effort. The PV 6222 can generate up to 100 bar (1500 psi) of pneumatic pressure and solves the transportation and health and safety issues arising from the field use of gas bottles and regulators. It features an innovative dual stage system, where a hand pump generates the pressure and a screw press intensifies the pressure. The PV 623 can generate up to 1000 bar (15000 psi) of hydraulic pressure without the need for priming and provides a stable set pressure within just one minute.

While being capable of stand-alone operation in a wide range of situations, the PV 62x pressure stations have been specifically designed for use with the DPI 620 advanced multi-function calibrator and interchangeable PM 620 pressure modules, to provide a multi-parameter calibration system with unique pressure generation and measurement capabilities. ATEX approval of the DPI 620 and the PM 620 is scheduled for later this year.
