Different types of Pressure Measurement Devices
Gravitational transducers
- A dead weight tester
- Manometer
Elastic Transducers
- Bourdon tube pressure gauge
- elastic diaphragm gauges
- bellow gagues
- Bellow gaugues to measure gauge pressure
- Bellow gauge to measure differential pressure
Strain gauge pressure cells.
-
