The Druck 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. Provides up to four times greater stability and higher accuracy than current pressure measurement technologies.
A simple screw fit 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.
FEATURES• 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
• Safe and Hazardous area versions available
• Fully interchangeable with no need for set-up or calibration -
