After more than half a century of development, the transmitter has experienced the development stage from hydropneumatic instruments, electric instruments, electronic analog instruments, digital intelligent instruments to the most advanced computer distributed control system. It has become an indispensable instrument in industrial production. Today we will take you to understand all aspects of the transmitter. First, the function of the transmitter In industrial production, after the measuring element detects the pressure, temperature, flow, liquid level and other parameters, the signal of the measuring element needs to be converted into a standard signal source (such as 4~20mA DC power supply) by the transmitter, and sent to the display instrument or regulating instrument for display, recording or adjustment. Therefore, the transmitter is not only a conversion medium, but also a medium. Transmitters are an indispensable part of modern industrial production. Second, the role of the transmitter Because the regulator is generally in the control room that is relatively far away, the transmitter has become a composite of the two functions of signal generation and transmission line drive, and has become the heart of the entire control device. Third, the type of transmitter According to the different measurement media, the transmitter can be divided into pressure transmitter, liquid level transmitter, temperature transmitter, temperature and humidity transmitter, differential pressure transmitter, soil moisture transmitter, etc. According to the difference in driving energy, the transmitter can be divided into pneumatic transmitter and electric transmitter. According to the different output signals, the transmitter can be divided into current output type transmitter, voltage output type transmitter and RS485 digital output type transmitter. As a transmitter manufacturing enterprise, Star Meter has always been committed to the production and research and development of transmitters.
