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
