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 related and different. Next, I will share with you briefly.

Sensor

Rika is a sensor manufacturer & solution provider of environmental and weather monitoring for 10+ years

A sensor is a device that converts a physical signal into an electrical signal, and is mainly composed of sensitive components, conversion components, conversion circuits and auxiliary power supplies. It has the characteristics of miniaturization, digitization, and intelligence.

Transmitter

Transmitter is an instrument that converts non-standard electrical signals into standard electrical signals. It is mainly composed of a measurement part, an amplifier and a feedback part.

The difference between sensor and transmitter

1. Wiring system and power supply: The sensors have two-wire, three-wire, and four-wire systems, some need additional power supply, and some do not need power supply. The transmitter is a two-wire system and the power supply and signal are the same group of wires.

2. Signal: The sensor output signal is a non-standard electrical signal, and the transmitter output is a standard electrical signal.
