What are the basic concepts and differences between sensors and transmitters

A sensor is a general term for a device or device that can be measured and converted into a usable output signal according to a certain rule. It is usually composed of sensitive components and conversion components. When the output of the sensor is a specified standard signal, it is called a transmitter.

The concept of a transmitter is an instrument that converts a non-standard electrical signal into a standard electrical signal, while a sensor is a device that converts a physical signal into an electrical signal. In the past, physical signals were often used, but now other signals are also available. The primary instrument refers to the field measuring instrument or the base control meter, and the secondary instrument refers to the instrument that uses the primary meter signal to complete other functions: such as control, Display and other functions.

What are the basic concepts and differences between sensors and transmitters

Sensors and transmitters are the concept of thermal instruments. The sensor converts non-electrical physical quantities such as temperature, pressure, liquid level, material, gas characteristics, etc. into electrical signals or sends physical quantities such as pressure, liquid level, etc. directly to the transmitter. The transmitter is to amplify the weak electric signal collected by the sensor in order to transfer or start the control element. Or a signal source that converts the non-electricity input from the sensor into an electric signal while amplifying it for remote measurement and control. The analog quantity can also be converted into digital quantity according to need. The sensor and transmitter together constitute a monitoring signal source for automatic control. Different physical quantities require different sensors and corresponding transmitters. There is also a transmitter that does not convert physical quantities into electrical signals, such as a “differential pressure transmitter” of a boiler water level gauge, which sends the lower water and upper steam condensate in the liquid level sensor to the meter pipe. On both sides of the bellows of the transmitter, the mechanical amplifier is driven by the differential pressure on both sides of the bellows to indicate the water level with a pointer. Of course, there is also a transmitter that converts electrical analog quantities into digital quantities. The above is just a conceptual illustration of the difference between a sensor and a transmitter.
