2-WIRE DIFFERENTIAL PRESSURE TRANSMITTERS
CURRENT OUTPUT
SPECIFICATION DATA & MOUNTING INSTRUCTIONS
GENERAL
The differential pressure transmitters of the DPIA series are
used for measuring differential pressure, positive pressure,
and vacuum. The transmitters are suitable for:
 air-conditioning,
 building
automation,
 environmental protection,
 valve and damper control,
 filter and blower monitoring,
 control of air flows.
