De Wit Pressure Gauges

Pressure gauges are mechanical instruments used to measure pressure, vacuum or differential pressure. To meet the various requirements in industrial and process instrumentation De Wit pressure gauges are available in different sizes, with different materials and with different measuring elements.

Models

De Wit 91(V) series – St.steel pressure gauges

St.steel bourdon tube pressure gauges for measuring air, water, oil and aggressive media that are not highly viscous or crystallising and that do not harm 316 SS. Ideal for corrosive environments, (petro)chemical industry, on- and offshore, environmental technology etc.
Suitable for pressures between 0-0,6 bar and 0-1600 bar
Higher ranges available with CrMo52/NiSpanC bourdon tubes
V = liquid filled execution, for applications with pressure pulsations/vibrations or for outside mounting

De Wit 91SF(V) series – St.steel solid front pressure gauges

Full safety pattern st.steel bourdon tube pressure gauges for measuring air, water, oil and aggressive media that are not highly viscous or crystallising and that do not harm 316 SS. Ideal for corrosive environments, (petro)chemical industry, on- and offshore, environmental technology etc. where increased safety is required. Full safety pattern with solid baffle wall between movement & dial and full blow out back (EN837-1, safety class S3).
Suitable for pressures between 0-0,6 bar and 0-1600 bar
Higher ranges available with CrMo52/NiSpanC bourdon tubes
V = liquid filled execution, for applications with pressure pulsations/vibrations or for outside mounting

De Wit 61R(R) series – Low pressure (capsule) gauges​

Low pressure diaphragm box (capsule) gauges for measuring low pressures in for example medical, vacuum or environmental technogoly. Suitable for dry air and non-aggressive gases only. Optional with 316 SS wetted pars (De Wit model 61RR) for applications with aggressive dry media that do not harm 316 SS.
Suitable for pressures between 0-xx mbar and 0-500 mbar.
Not available with liquid filling.

De Wit 4501R(S) series – Test gauges

Bourdon tube test gauge for applications where high accuracy of cl. 0,25 is required. For example for calibration of pressure gauges or pressure transmitters, in process control.
Suitable for pressures between 0-0,6 bar and 0-1600 bar.
V = liquid filled execution, for applications with pressure pulsations/vibrations or for outside mounting

De Wit 181R(RV) series – Precision gauges

Bourdon tube precision gauges for exact pressure measuring of air, water, oil or other media where higher accuracy of cl. 0,6 is required.
Optional 316 SS wetted parts (De Wit model 181RR) for applications with aggressive media that do not obstruct the measuring system and are compatible with 316 SS.
Suitable for pressures between 0-0,6 bar and 0-2000 bar.
V = liquid filled execution, for applications with pressure pulsations/vibrations or for outside mounting
