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.
