Thus the instrument issuitable for liquid and gaseous media, also in aggressiveenvironments.WIKA manufactures and qualifies the pressure gaugein accordance with the standards EN 837-1 andASME B40.100. This instrument has as safety function ablow-out device with blow-out plug on the back of the case. Inthe event of a failure, overpressure can escape there.The model 233.50 with liquid-filled case is suitable for highdynamic pressure loads and vibrations.Scale ranges of 0 0.6 to 0 1,600 bar [0 . 10 to0 . 20,000 psi] ensure the measuring ranges required for awide variety of applications.WIKA data sheet PM 02.02 01/2021Data sheets showing similar products:Stainless steel, safety version; model 232.30; see data sheet PM 02.04Bourdon tube pressure gauge with switch contacts; models PGS23.100 and PGS23.160; see data sheet PV 22.02Pressure gauge per EN 837-1 with mounted diaphragm seal; model DSS27M; see data sheet DS 95.12Page 1 of 11
