Druck PM620 Specifications

PM620 TERPS High Accuracy Pressure Modules

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

Features

• Total uncertainty from 0.0125% FS

• Temperature compensated accuracy from

-10°C to 50°C (-14°F to 122°F)

• Simple screw t - 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

• Safe and Hazardous area versions available

• Fully interchangeable with no need for set-up or calibration

The PM620 TERPS is the latest development in resonant silicon pressure sensor technology incorporating a

number of key innovations to allow pressure re-ranging of compatible equipment. A simple screw t makes both

the pressure and electrical connections without the need for tools, sealing tape, cables or plugs and digital characterisation allows interchangeability without set-up or calibration.

Notes:

1. The reading can be referenced to ambient air pressure via a software feature of the DPI620 Genii, allowing the same module to be switched between absolute and sealed gauge measurement.

2. NLH&R Non-linearity, hysteresis and repeatability to reference standard.

3. Total uncertainty includes reference standard uncertainty, NLHR over specied range and 1 year drift.
