Diaphragm pressure gauge type MPE

Product description

Possible areas of application Diaphragm pressure gauge type MPE

Pressure gauges with horizontal diaphragm allow to find suitable versions for even difficult kinds of media, such as aggressive, contaminated or viscous media. The stainless steel bayonet ring case is designed for applications where a rust resistant, sealed case of high chemical resistance is required (dirty damp, or corrosive atmosphere).



Display ranges
Display ranges from 0..10 bar up to 0…40 bar, with PTFE-foil starting at 0...40 mbar; filled starting at 0...40 mbar available.

Connection threads and materials
Type 316L pressure gauges with stainless steel connection are available with a stainless steel diaphragm (40 to 250 mbar) or a Duratherm diaphragm (0.4 to 40 bar). In addition, they can optionally be produced with PTFE lining.
