The Intrinsically Safe version of the DPI 620 Series is now available allowing configuration and multi-function calibration in hazardous areas. The ATEX and IECEx certification allows the instrument to be employed globally in Zone 0 areas. The certification also applies to the instrument’s battery pack, permitting hot swapping within hazardous locations. The approval now further extends the range of potential applications of the powerful communicator/calibrator, especially in the oil and gas and process sectors. As with all instruments in the DPI 620 family, the IS version is rugged and compact and weather-proofed to IP65.

There are three pressure generation stations, also available in ATEX approved versions for stand- alone use in hazardous areas:

PV 621 - pneumatic pressure generator for pressures 95% vacuum to 20 bar (300 psi)

PV 622 - pneumatic pressure generator for pressures 95% vacuum to 100 bar (1500 psi)

PV 623 - hydraulic pressure generator for pressures up to 1000 bar (15000 psi).

Each pressure station is designed for stand-alone operation as a pressure generator and can replace conventional hand pumps and gas bottles to provide greater efficiency and ease of use. They can be used on the workbench or combined with a reference instrument, such as the DPI 104 they can be used as comparators and pressure calibrators.

The technically advanced GE Druck DPI 610 and DPI 615 portable calibrators are the culmination of many years of field experience with the company.

These self-contained, battery powered packages contain a pressure generator, fine pressure control, device energising (not IS version) and output measurement capabilities, as well as facilities for 4 to 20 mA loop testing and data storage. The rugged weatherproof design is styled such that the pressure pump can be operated and test leads connected without compromising the visibility of the large dual parameter display. The mA step and ramp outputs and a built-in continuity tester extend the capabilities to include the commissioning and maintenance of control loops.

The DPI 610/615 low pressure calibrator versions enable the end user to calibrate draft range instrumentation in the field.
