How to connect pressure sensor, pressure transducer or pressure transmitter to industrial instrumentation or PLC?
① Pressure sensor 4-wire Millivolt-output
② Pressure transducers 3-wire Voltage-output
③ Pressure transmitters 2 wire 4-20mA current-output
The diagrams below show how a Milli voltage-output pressure sensor, Voltage-output pressure transducer or Current-output pressure transmitter can be connected to a programmable logic controller (PLC) or meter to monitor pressure in a typical industrial equipment or process control application.
