Type MRE-MREG Bourdon Tube Pressure Gauges With Casing Filling

DATASHEET

SIKA quality pressure gauges in industrial version with 100, 160 or 250 mm stainless steel casing are suitable for pressure measurement of gaseous and liquid media, but not for highly viscous or crystallising media.

DIN display ranges available from -1...0 bar up to 0...1,600 bar (up to...1,000 bar, brass connection; up to...1,600 bar with stainless steel connection). We manufacture special ranges on request.

The stainless steel casing is available either as a bayonet ring case (type MRE) or as a cramped-on ring case (type MRE-G)

» Suitable for outdoor use - closed system
» Casing completely stainless steel
» Without electrical auxiliary energy
