DPI 610/615 Portable Pressure Calibrators are the culmination of many years of field experience with the company’s DPI 600 series. 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. DPI 610IS and DPI 615IS are available as complete maintenance tools and portable calibration standards for pressure instruments and control loops in hazardous ’Zoned‘ areas. Certified to BASEEFA and CENELEC standards, the DPI 610IS and DPI 615IS can reduce response times to breakdown.
