Technical Data
Description
The PR3200 differential pressure transmitteruses two titanium alloy pressure sensors, offeringhigh stability and performance with true wet/wetoperation, suitable for use with all liquids andgases compatible with stainless steel and titanium.
The unique Silicon-on-Sapphire sensor technology provides
outstanding performance and gives excellent stability overa wide temperature range. The advanced sensor design
consists of a piezoresistive silicon strain gauge circuit, which isepitaxially grown onto the surface of a sapphire diaphragm toform a single crystalline structure.The sapphire sensor element
is then molecularly bonded to a titanium alloy sub-diaphragm.
This enables the sensor to endure higher over- pressures andprovides superb corrosion resistance. The completed sensor
exhibits virtually no hysteresis and excellent long-term stability.
With outstanding insulation properties, the sapphire substrate
allows the sensor to operate over a very wide temperature

range without loss of performance.
Applications include flow measurement with orifice plates andmass flow meters, plus static differential pressure measurement
and control in combustion chambers, also condition monitoring
and filter monitoring in high pressure hydraulic systems or
any application on liquid or gas requiring reliable differential
pressure measurement. Electrical connector is DIN plug andsocket. Access to zero and span adjustment is by removing
top plate for easy on-site adjustment. Pressure connection
as standard is via two 1/4” BSP female connections. Mounting
plate is available for bulkhead mounting. Ranges available from0-500 mbarDP to 0-200 barDP
An optional ATEX and IECEx approved version of this productis available for explosion protection for flammable gases (zone0), dusts (zone 20) and mining areas (group I M1).
