Protran ® PR3202 Low Pressure Differential Transmitter
Technical Data
Description
Our low range air differential pressure transmitter
provides an accurate solution for low pressure
sensing with ranges available from 0-5 mbar to0-1,000 mbarDP. Incorporating the latest siliconsensor and electronics technologies, these
4-20 mA transmitters are fully temperaturecompensated for unrivalled stability at very low
pressure.
Housed in an RFI shielded wall mountable box for EMC
protection, these transmitters combine precise measurement
for control at very low pressures, with the robustness andflexibility for industrial and commercial installations. An
optional heavy-duty aluminium die-cast housing is available forthe harshest environments.

and control, in combustion chambers and clean rooms, or any
application on air or gas requiring reliable ultra-low differential
pressure measurement. Access to screw terminal electricalconnections and to zero span potentiometers is by removing
the front covers, making installation and on-site adjustment.
Cable entry is through a compression seal gland, or optional
M20 conduit fitting. Standard pressure connections are topush-on hose fittings for 4mm ID hose. Ranges available
from 0-5 mbar to 0-1,000 mbar in DP, gauge reference or bidirectional. Ultra-low pressure ranges from 0-25 Pa are alsoavailable.
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).

Applications include flow measurement with pitot tubes, orificeplates and mass flow meters, plus static pressure measurement
