Liquid-filled pressure gauges are used in applications that involve high dynamic shock and vibration loading. The filling liquid dampens the vibrations that occur and thus takes the load off the mechanical components of the pressure gauge. Depending on …

Verification or calibration?
| Christian Elbert | Know-howIn general usage, the term "verification" is often mixed up with "calibration". In contrast to calibration, where the deviation of a measured value is determined and certified from a standard, verification goes well beyond that and is only in very special cases a legal …
How do diaphragm seals work?
| Jennifer Breunig | PressureDiaphragm seals, also known as chemical seals or remote seals, are used for pressure measurements when the process medium should not come into contact with the pressurised parts of the measuring instrument. A diaphragm seal has two primary tasks: 1. Separation of …
Electronic pressure sensor/pressure transmitter or mechanical pressure indicator?
| Stefan Heusel | PressureFor some years now, it has been possible to increasingly automate production processes, and by doing to to achieve substantial cost reductions in some cases. This raises the question: does it still make sense to use mechanical pressure measuring instruments? The …
