With the DPI 620 Genii, DRUCK sets a standard in portable calibration. This ultra-compact electrical, frequency and temperature calibrator and HART communicator provides simultaneous measurement and encoder functions for setting, testing and calibrating process instruments including pulse generators, transducers, gauges/indicators, switches, proximity detectors, counters, RTD, thermocouples and valve positioners, etc.
 

The PV624 uses a hybrid approach to pressure control thereby leveraging the benefits of both manual and automatic control technology

• Fully automated & highly stable (50ppm/0.005%) pressure control when approaching setpoint. No manual adjustments for leaks or adiabatic influences required
• Superior “time to setpoint” (for both small & large volumes) versus the fully manual or fully electric portable calibrators
• Maximum flexibility with removable pressure modules (PM620/PM620T) from 700mbar up to 20bar (including pseudo readings) allowing you to optimise your accuracy & control stability for your intended pressure range
• Excellent battery life (minimum 8 hours continuous usage) and mechanical robustness versus comparable electric calibrators. Charging dock and spare batteries available for in-field swap outs where necessary
• Available alongside the familiar DPI620G with new & improved user interface featuring an intuitive calibration wizard to significantly improve product efficiency

Three pressure generating stations are also available in ATEX-compliant versions as stand-alone units for hazardous areas:

PV 621G - Pneumatic pressure generator for pressures 95% negative up to 20 bar (300 psi).

PV 622G - Pneumatic pressure generator for pressures 95% negative up to 100 bar (1500 psi)

PV 623G - Hydraulic pressure generator for pressures up to 1,000 bar (15,000 psi)

Each pressure station is designed to operate independently as a pressure generator and can replace conventional hand pumps and gas cylinders, providing greater efficiency and ease of operation. The pressure generators can be used as comparators and pressure calibrators on a bench or in combination with a reference instrument such as the DPI 104.

Combining one of the pressure stations with a PM 620 pressure module and the DPI 620 calibrator creates a unique, powerful, stand-alone pressure calibrator.

The PM620 pressure module from DRUCK offers the highest accuracy and stability thanks to the new resonance silicon pressure sensor technology. The pressure modules allow easy pressure range conversion of compatible pressure calibrators from the DPI 620Genii and DPI612 Flex series. The device-specific calibration data is located directly on the sensor in the pressure module. Thus, a simple change of the measuring ranges is possible, which brings great flexibility.

• Total measurement uncertainty of 0.0125 % FS
• Compensation from -10 ° C to 50 ° C (14 ° F to 122 ° F)
• Ranges from 1.2 bar to 100 bar abs. (17.5 psi to 1500 psi)

The DPI 610E portable pressure calibrator combines pressure generation and measurement of the electrical output signal with significantly improved pump functions and a powerful user interface. The DPI 610E combines effortless pressure generation with highly accurate pressure measurement down to 0.025% of full scale and allows selection from 8 measuring ranges up to 35 bar (pneumatic version, incl. barometer) or 11 measuring ranges up to 1000 bar (hydraulic version).

The supply of the test item with voltage and current as well as the measurement of the output signal ensures the electrical function. Special functions such as documenting and exporting measured values, leak and switch tests are available as standard. The robust and resistant pressure calibrator has a large and high-contrast touch screen and a newly designed user interface and additional keys.

To extend the measuring ranges, the DPI 610E is compatible with the PM 700E pressure modules, while the RTD temperature probe enables temperature measurement. The HART interface comes as standard.

These fully self-contained pressure test and calibration systems feature interchangeable pressure modules for flexible range measurements, generate pneumatic or hydraulic pressure, measure process signals and provide power. They provide all the conveniences of the DRUCK DPI 610/615 series, plus enhanced pressure generation capabilities, improved accuracy and simplified touch-screen operation.
