Signal Transmission - Standards

Standard signals used for transmission from sensor to controller.

Standards used for signal transmission from sensor to controller in industrial processes:

Signal Transmission from Sensor to Controller
Pneumatic pressure 3 - 15 psig,  20 - 100 kPa
Voltage 0 - 10 V (or 0 - 5 V)
Electric current (direct current) 4 - 20 mA

More and more sensor to/from controller transmission are now done with "smart" equipmement and wire/wireless data communication.
