PR3200 DIFFERENTIAL PRESSURE TRANSMITTER
ACCURATE AT VERY WIDE DP RANGE
HIGH STABILITY and REPEATABILITY
WET / WET OPERATION
4-20mA TWO-WIRE OUTPUT
ZERO + SPAN ADJUSTMENT ON-SITE
RANGES 250mbarDP to 200barDP
UNI + BI-DIRECTIONAL OPERATION
DESCRIPTION
The PR3200 Differential Pressure Transmitter uses two matched ceramic pressure diaphragms, offering high
stability and performance with true wet/wet operation, suitable for use with all liquids and gasses compatible with
stainless steel and alumina. Flush diaphragm models are available with integral or remote pressure diaphragms for
hygienic applications.
Applications include flow measurement with pitot tubes, orifice plates and mass flow meters, plus static differential
pressure measurement and control in combustion chambers and clean rooms, also condition monitoring and filter
monitoring in high pressure hydraulic systems or any application on liquid or gas requiring reliable differential
pressure measurement.
Electrical connection is DIN plug and socket, access to zero and span adjustment is made by removing top plate
for easy on-site adjustment.
Pressure connection as standard is via two ¼"BSP female connections.
Mounting Plate available for stand-pipe or bulk-head mounting.
Ranges available from 0-250mbarDP to 0-200barDP.
