The sensor and transmitter are thermal instrumentation concept

The sensor and transmitter are thermal instrumentation concept. Sensors are the non-electric quantities such as temperature, pressure, level, material, gas characteristics into electrical signals or physical quantities such as the pressure, level, etc. directly to the transmitter. Transmitter is Crank Position Sensor to the weak signal amplification in order to transfer or start control components. Or to the non-power sensor input into electrical signals while amplifying remote measurement and control in order for the signal source. According to the analog can be converted into a digital value. Together constitute a sensor and transmitter control monitor signal source. Require different quantities of different Crank Shaft Position Sensor and the corresponding transmitter. There is also a transmitter is not a physical quantity into an electric signal, such as A boiler water level of the "pressure transmitter" he is to the lower level sensor in the water and steam condensate water through the upper portion of the instrument tube to the the transmitter side bellows, the bellows side of the differential to drive the mechanical amplification means a pointer indicating a distance meter level. Of course, there are quantitative replaced the electrical simulation can also be called the digital transmitter. These are just a conceptual description of the difference between the sensor and transmitter.
