"Driving Cost out of Your Business"



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.

DPI 620 Series - Advanced Modular Calibration and HART® Communication System

Modularity brings a whole new perspective to multi-function test instruments, calibrators and HART communicators.

The DPI 620 Series uses three basic components to provide the multifunctionality to perform duties formerly requiring a wide range of different instruments.

At the heart of this system is the DPI 620, an ultra-compact electrical, temperature and frequency calibrator and HART communicator, which provides simultaneous measurement and source capabilities with a fully featured HART digital interface. It integrates with pressure modules and pressure generation stations to form uniquely capable pressure test and calibration systems.

Product Description

  • The DPI 620’s basic component is an ultra-compact, electrical, frequency and temperature calibrator and HART communicator.
  • Pressure measurement is provided by interchangeable pressure modules that can be attached to the calibrator by a pressure module carrier.
  • If pressure generation is required the calibrator and pressure module can be attached to one of three pressure generation stations, to form a fully-integrated pressure calibrator.
  • Multichannel datalogging, device error calculation and compatibility with PC calibration and asset management software are just some of the powerful built-in diagnostic and documenting tools.
  • The DPI 620 is also a fully featured HART communicator with device descriptions for all registered HART devices. mA measurement, loop power, integral 250 ohm resistor and sourcing of the primary variable for pressure, temperature and electrical device calibrations are standard features. Software and device library updates are free of charge by simple file download.
  • The DPI 620 CE version has all the power of a pocket PC or PDA. it is now possible to carry all supporting safety and procedural documentation including Word, PDF, Excel, Power Point and images files in a calibrator/HART communicator.
  • The DPI 620 IS version has been approved for use in potentially explosive atmospheres (ATEX and IECEx certification)
