The differential pressure transmitters of the DPIA series are used for measuring differential pressure, positive pressure, and vacuum. For over-pressure (static pressure) connect the + pressure port to the pressure supply, and leave the - port open to the air. For vacuum pressure connect the - port to the pressure supply and leave the + port open to the air. The transmitters are suitable for:

• air-conditioning,
• building automation,
• environmental protection,
• valve and damper control,
• filter and blower monitoring,
• control of air flows.
