The Difference between the Sensor and the Transmitter Is Related.

Sensors are the general term for devices or devices that are subject to measurement and conversion to available output signals according to certain laws, usually consisting of sensitive components and conversion elements, WRN-231 thermocouples, WZP-130 thermoresistors. When the output of the sensor is a specified standard signal, it is called a transmitter, such as the Maoshan brand MS-WB temperature transmitter, MS-YB pressure transmitter, MS-YBL level transmitter. 

The concept of transmitters is an instrument that converts non-standard electrical signals into standard electrical signals, while sensors are devices that convert physical signals into electrical signals, which used to talk about physical signals, but now other signals. A meter refers to the field measuring instrument or base control meter, the second instrument refers to the use of a table signal to complete other functions: such as control, display and other functions of the instrument.

Sensors and transmitters are supposed to be the concept of thermal instruments. Sensors are non-electrical physical quantities such as temperature, pressure, level, material, gas characteristics, etc. into electrical signals or physical quantities such as pressure, level, etc. directly to the transmitter. A transmitter is a weak electrical signal captured by the sensor to transmit or start the control element. Or convert the non-charge of the sensor input into an electrical signal at the same time zooming in for remote measurement and control of the signal source. You can also transform the analog amount into a digital quantity as needed. Together with the transmitter, the sensor forms the monitoring signal source for automatic control. Different physical quantities require different sensors and corresponding transmitters. There is also a transmitter is not to transform the physical amount into electrical signals, such as a boiler water meter "differential pressure transmitter", he is the lower water in the liquid level sensor and the upper steam condensate through the meter tube to the two sides of the transferpipe, with the difference pressure on both sides of the bellows to magnify the mechanical device with a pointer to indicate the water level of a distant instrument. Of course, there is also the electrical analog amount into a digital amount can also be called transmitter. The above only conceptually illustrates the difference between a sensor and a transmitter.
