The air differential pressure transmitters of the 984M series are used for measuring differential pressure, positive pressure and vacuum.

The air differential pressure transmitter can selected between two adjoining pressure ranges in same unit.

The air differential pressure transmitter have selectable output via jumper, 0-10 Vdc or 4-20 mA output, 3-wire.

The air differential pressure transmitter is also available with 4-20 mA output, 2-wire.
