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.
