Pressure measurement

Operating pressure ranges
A 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 pressure
Proof pressure tested to 1.5 x FS pressure

Overpressure
The operating pressure range can be exceeded by 1.5 x FS pressure to 1600 bar max, whichever is less. 

Secondary containment pressure
The transmitter will safely contain up to 1150 bar maximum without leakage of pressure media.

External case pressure
Tested to 300 bar with negligible change in calibration.

Pressure media
Fluids compatible with a fully welded assembly of Inconel 625 and Stainless Steel.

Transmitter Supply Voltage
10 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 current
4 to 20mA (2-wire) proportional for zero to full scale pressure
