The differential suppliers of pressure transmitters of the 985M series are used for measuring differential pressure, positive pressure and vacuum of air and non aggressive gases. They offer 2 pressure ranges which can alternatively be selected by a jumper. The IP65 body protects the industrial pressure transducer even in difficult environments.

Monitoring gaseous, non-aggressive media. Possible areas of application are:
 air-conditioning and washing rooms
 building automation
 environmental protection
 professional fan and professional blower control
 cock and flap control
 professional filter and blower monitoring
 fluid and level monitoring
 control of air flows

For optimum adaptation to the pressure application, the
professional transmitter can be switched between two pressure ranges.
The factory setting is the sensitive range 1, which is selected
by professional fitting a jumper. Removing the jumper activates the
non-sensitive range 2.

The output signal of the 3-wire version is configurable. The
factory setting is for a 0 ...10 Volt output signal, but this can be
changed to 4 ... 20 mA by removing the jumper. The 2-wire
version is only available with a 4 ... 20 mA output signal.
