WIKA 732.51.2170

集成静压压力表和阀组紧凑型不锈钢差压压力表

Compact Differential Pressure Gauges PN 40
with combined working pressure gauge and
integrated pressure equalizing valve, Model 732.51.2170

Typ 732.51.2170 mit Option Ferngeber für Differenzdruck und
Messumformer für Betriebsdruck

   Applications
    For measuring the differential between two pressures, preferentially for filling level measurement in cryotechnology
     For monitoring and controlling the static working pressure (basis pressure)
Special Features

   Special Features
     Differential and working pressure registered centrally in one unit
     Reduced number of sealing and measuring points
     No separate installation of working pressure gauge and pressure equalizing valve, reduced installation effort and costs for plant operators
     Guaranteed leakage proof through helium testing⇒ leak rate q ≤ 10-8 mbar l/ s
     Service-friendly snap bezel case
