Differential pressure transmitter with automated offset compensation

The differential pressure transmitters of the 984 series are used to measure differential pressure, overpressure and vacuum.
They provide up to 8 pressure ranges and 2 output signals, which are easily selectable by jumper or rotary selector switch.


Switching output
To give a switch signal at an user defined pressure level the transmitter has an adjustable transistor switching output (NPN NO) with a maximum switching capacity of 30 VDC/100 mA.
