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