The Difference between Transmitter and Sensor
|
The Difference between Transmitter and Sensor The sensor is the device that is able to be measured and convert the output signal according to certain rules. It is usually consist of sensitive components and conversion components. When the sensor output signal is the standard signal, then the sensor is known as the transmitter. The transmitter is converting non-standard signals into standard electrical signal instruments, while sensor converts the physical signal into electrical signal. An instrument refers to the on-site measuring instruments or base control table, the second instrument signal refers to the use of a table to complete other functions: such as control, display and other functions. The sensor and transmitter are concept of thermal instrumentation. Sensors convert 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 send to the transmitter. Transmitter amplify the weak signal which is collected by sensor in order to transfer or start control components. According to requirement it also can convert analog quantity to digital quantity. The sensor and the transmitter constitute a control monitor signal source together. Different quantities require different sensors 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", which is to the lower level sensor in the water and steam condensate water through the upper portion of the instrument tube to 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. |
