Diaphragm Pressure Gauges (Horizontal)

Diaphragm pressure gauges with horizontal diaphragm are suitable for the measurement of pressure and vacuum between 0 – 10 mbar and 0 – 40 bar for gaseous, liquid, also highly viscous and crystallised media that do not corrode steel, stainless steel or PTFE. The diaphragm pressure gauges stand out due to their protection against increased overpressure. Special materials of the wetted parts are available. An installation of electrical additional accessory is possible.
