PDBH – Diaphragm Type Gauge

All stainless steel pressure gauge suitable for measurement tomaximum pressure of 2 500 kPa especially in corrosive environmentswhere a pressure element of exotic materials is required.Also suitable where start up pressures are significantly higherthan operating pressures and to measure viscous fluids or fluidswith suspended solids.

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

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
