Setra System Model 270 - Manual (Page 4)

OPTION #3
Uses a single, ground referenced power supply for excitation and either a single, isolated readout with a
bipolar switch that “breaks before makes” both the + output and - output of each pressure transducer, or a
single data acquisition system with a multiplexer (MUX).
NOTE: The shield is internally commoned to the case and pressure port of the transducer. When the
shield is connected to ground the case and pressure port of the transducer will also be commoned to that
ground.
