Multifunction Calibrators

Druck's DPI620G combines an advanced multi-function calibrator and HART/Foundation Fieldbus communicator with world-class pressure measurement and generation. ATEX, IECEx and ETL approved intrinsically safe versions are available for use in hazardous areas. 

This ultra-compact electrical, frequency and temperature calibrator with full HART communicator and optional Foundation Fieldbus communicator provides simultaneous measurement and source capabilities for the setup, testing and calibration of most types of process instruments including transmitters, transducers, gauges/indicators, switches, proximity detectors, counters, RTDs, thermocouples and valve positioners.

With four pressure generating base stations, offering efficient pressure generation up to 1,000 bar, with optional safe and hazardous environment configurations: 

• The PV621, a pneumatic pressure generator for pressures 95% vacuum to 20 bar (300 psi)
• The PV622, a pneumatic pressure generator for pressures 95% vacuum to 100 bar (1,500 psi)
• The PV623, a hydraulic pressure generator for pressures up to 1,000 bar (15,000 psi)
• The PV624, a portable hybrid pressure controller, combining manual and automatic technologies, up to 20 bar (300 psi)

Each pressure station is designed for stand-alone operation as a pressure generator and can replace conventional hand pumps to provide greater efficiency and ease of use. They can also be used on the workbench as comparators. Combining any of the pressure stations with a PM620 pressure module and the DPI620 calibrator creates a uniquely capable, self-contained pressure calibrator.

The PM620 is the latest development in digital output sensor technology incorporating a number of key innovations to allow pressure re-ranging of compatible equipment. A simple screw fit makes both the pressure and electrical connections without the need for tools, sealing tape, cables, or plugs and digital characterization allows interchangeability without set-up or calibration. The PM 620 is also available in an intrinsically safe version, the PM 620-IS, for use in hazardous environments.

Features include:

• Fully interchangeable with no need for set-up or calibration
• Simple screw fit - hand tight no tools required
• Ranges from 25 mbar to 1,000 bar (10 inH2 O to 15,000 psi)
• Accuracy from 0.005% FS
• Safe and Hazardous area Versions available
• Pressure ranges from -14.5 to 15,000 psi
• Gauge or absolute pressures
• IS model is ATEX and IEC approved Intrinsically Safe

PM620 now incorporates our unique range of TERPS resonant silicon pressure sensor technology, the PM620T and the PM620TS intrinsically safe version. Providing up to four times greater stability and higher accuracy than current pressure measurement technologies.

Features include:

• Total uncertainty from 0.0125% FS
• Temperature-compensated accuracy from -10°C to 50°C (-14°F to 122°F)
• Simple screw fit - hand tight no tools required
• Ranges from 1.2 bar to 100 bar (17.5 psi to 1500 psi)
• Compatibility with pressure calibrators such as DPI612 and DPI620G/DPI620G-IS series
• Fully interchangeable with no need for set-up or calibration

The MC620 module carrier attaches to the head of the DPI620G to provide two independent pressure measurement channels. These can be fitted with any PM620 pressure module from 25 mbar to 1,000 bar (10 inH2 O to 15,000 psi). A simple screw fit means no tools are required and ensures both a high integrity pressure seal and a reliable digital interface. Even the pressure adapters are interchangeable and only require a finger tight fit. The carrier is designed for pressure safety and will automatically seal if a module is not fitted or if the user attempts to remove it.

Features include:

• 2 independent pressure channels
• Simple to re-range
• Pressure protection
• Safe and Hazardous (IS) versions available

IO620-AC - Replacement AC voltage measurement probe Attaches to the DPI620G, 30 V sockets to provide 300 VAC true rms measurement. Is supplied as standard with all new DPI620G

IO620-CASE-1 - Carrying case Protective carrying case with belt loop, shoulder strap and large detachable pocket for test leads and accessories

IO620-CASE-2 - System carrying case Protective carrying case for system components including the DPI620G, MC620G, PM620 modules, test leads, hose and adaptors

IO620-CHARGER - Battery charging station External battery charging station allows a spare battery to be charged independently of the DPI620G for minimum instrument downtime. Power is provided by the standard mains adaptor (P/N I0620-PSU). A complete charge cycle takes approximately 6.5 hours. The charging station can be connected to a USB port to provide a top-up charge (full charge in 13 hours)

IO620-USB-PC - USB cable Connects the DPI620G or DPI620G-IS to a PC

IO620-IDOS-USB - IDOS to USB converter Allows connection of an IDOS universal pressure module to the DPI620G. P/N IO620-USB-PC is also required to connect the converter to the DPI620G USB port. (not compatible with DPI620G-IS)

IO620-USB-RS232 - USB to RS 232 cable Connects the DPI620G to an RS 232 interface (not compatible with DPI620G-IS)
