Not much, really. All three are electronic pressure sensing devices. Technically, a transducer measures pressure or another physical property (load, force, etc.) and converts that reading into an electronic signal like 4 … 20 mA or DC 0 … 5 V. A transmitter does that too, but with amplification and modification, then sends that signal to a receiver. Manufacturers do not always differentiate between the two, and some users simply call any pressure device with a wire a pressure sensor.

The three most-common pressure measurement principles in pressure sensors are thin-film, thick-film, and piezoresistive. Each has its own advantages and disadvantages. The standardized pressure connection directs the pressure being measured onto the pressure sensor element. The electronics of the pressure sensor then converts the signal into a scaled signal, which is passed on to the subsequent signal evaluation via a standardized connector or cable.

Zero-point drift, also called zero-point error, is caused by aging of the electrical components through temperature cycling and load cycling.

No. All three wires must be connected for a 3-wire transmitter to work properly.
