Differential or Static Pressure Transmitters
Model Chart
Specifications
The P323 Series differential or static pressure
transmitters have been designed to sense
differential or static pressure across fans, coils,
filters, or between two reference points and to
transmit a 3 to 15 psig signal to controlling and
indicating devices such as receiver controllers,
receiver gages, and sensitive pressure switches.
These devices are one-pipe transmitters which
require an external restrictor in the supply line.
Their design features pneumatic feedback, which
ensures accuracy and stability over the entire
operating range. Mounting ears are provided for
strain-free mounting on ducts or other flat
surfaces.
Features:
• Permits remote readout and control of differential or static
pressure of air.
• Five different ranges permit proper match of transmitter
range to various applications.
• Ball-in-seat pneumatic feedback assures linearity and
responsiveness.
• Field-accessible “zero” adjustment.
