Q:How is pressure measured with a diaphragm pressure gauge?

A:In diaphragm pressure gauges, the pressure is transmitted via a wave-shaped diaphragm to a link, which transfers the pressure to the movement.

Q:When does it make sense to use a diaphragm pressure gauge?

A:Diaphragm pressure gauges are used when Bourdon tube pressure gauges reach their limits. They can be used at particularly low pressures and with critical media. In addition, they feature high overload safety.
