Pressure difference measurement arrangement; has deflection arrangement mounted on coupling arrangement between mechanical indicator and pressure transducer

摘要

The arrangement has a pressure transducer element (2) that converts the pressure difference into a deflection (13), a conversion arrangement (3,4) that converts the deflection into an electrical signal and a mechanical indicator (5,6) coupled using a coupling arrangement (8,9) to a pressure transducer element. The conversion arrangement is mounted on the coupling arrangement. The coupling arrangement is rotatably linked about an axle (7) on which the conversion arrangement is mounted. The pressure transducer may include a permanent magnet and a Hall sensor.
