Relationship between sensors and differential pressure transmitters????
A differential pressure transmitter is a signal conversion device for sensors, and it belongs to secondary instruments
Sensor: A device or apparatus that can detect a specified quantity to be measured and convert it into a usable signal according to certain rules; it usually consists of a sensitive element and a conversion element； Transmitter: capable of converting the signals transmitted by sensors into standard output signals
Reply 1# Air separation technology* Sensor: Measures and converts signals. Differential Transmitter: Transmits the acquired signals to the control center
That should make it easier for you to understand – a transmitter consists of a sensing part and an electronic component section. The sensing part detects the specified quantity being measured and converts it into a usable signal according to certain rules, while the electronic component processes these signals into standard signals for output!
Sensors come into contact with the medium, while transmitters do not
