Description
All stainless steel pressure gauge suitable for measurement
to maximum pressure of 2 500 kPa especially in corrosive
environments where a pressure element of exotic materials is
required. Also suitable where start up pressures are significantly
higher than operating pressures and to measure viscous fluids or
fluids with suspended solids.

Scale Ranges
Flange size is determined by the pressure range
0-40 to 0-400 mbar (150mm diaphragm
0-60 to 0-2500 kPa (100mm diaphragm)
or equivalent other units of pressure or vacuum
Working Pressure
Steady: full scale value
Fluctuating: 0,9 x full scale value
Accuracy
100 mm & 150 mm 1,6 % FSD
Temperature Range
Ambient temperature -25° C to +60° C
Medium temperature to 100 °C
Note: minimum temperature should not be less or equal
to the freezing point of the filling fluid.
Higher temperatures can be accommodated with heat
reducing devices
Weather Protection
IP 54
