What is the difference between a sensor and a transmitter?
Both the sensor and the transmitter play an important role in the field of automatic control. The transmitter is developed from the sensor. They are both related and different. Next, I will simply share it with you.
Sensor
A sensor is a device that converts physical signals into electrical signals, and is mainly composed of sensitive elements, conversion elements, conversion circuits and auxiliary power supplies. It has the characteristics of miniaturization, digitization and intelligence.
The transmitter is an instrument that converts non-standard electrical signals into standard electrical signals, and is mainly composed of a measurement part, an amplifier and a feedback part.
Difference Between Sensor and Transmitter
1. Wiring system and power supply: The sensor has two-wire system, three-wire system, and four-wire system. Some require additional power supply, and some do not require power supply. The transmitter is a two-wire system and the power supply and signal are the same group of wires.
2. Signal: The signal output by the sensor is a non-standard electrical signal, and the output of the transmitter is a standard electrical signal.
