Operating pressure rangesA full scale (FS) pressure range may be specified between 0 - 228 bar and 0 - 1035 bar, sealed gauge (See ordering information for available ranges).
Proof pressureProof pressure tested to 1.5 x FS pressure
OverpressureThe operating pressure range can be exceeded by 1.5 x FS pressure to 1600 bar max, whichever is less.
Secondary containment pressureThe transmitter will safely contain up to 1150 bar maximum without leakage of pressure media.
External case pressureTested to 300 bar with negligible change in calibration.
Pressure mediaFluids compatible with a fully welded assembly of Inconel 625 and Stainless Steel.
Transmitter Supply Voltage10 to 32 VDC. The minimum supply voltage that must appear across the transmitter terminals is 10 VDC. and is calculated by: VMIN = VSUP - (0.02 x RLOOP)
Supply sensitivity<0.005% F.S./Volt.
Insulation resistance>100M Ohm @ 500 Vdc
Output current4 to 20mA (2-wire) proportional for zero to full scale pressure
