A transmitter is a converter that converts the output signal of a sensor into a signal that can be recognized by the controller (or amplifies the non electrical input of the sensor into an electrical signal for remote measurement and control). A transmitter converts non-standard output signals into standard signals based on sensors. As the name suggests, a transmitter means “change” and “send”. The so-called “change” refers to the transformation of various physical quantities from sensors into an electrical signal. For example, using a thermocouple to convert temperature into potential. The so-called “sending” refers to unifying the electrical signals from sensors through electronic circuits (such as 4-20MA) in order to facilitate the reception and transmission of various transformed electrical signals by other instruments or control devices. The method is achieved through multiple operational amplifiers. This combination of “transformation” and “transmission” forms the most commonly used transmitter in modern times. Sometimes the concept of sensors and transmitters has a certain degree of universality because the output signal of most modern sensors is already a signal that can be accepted by a universal controller, and this signal can be directly recognized by the controller without being converted by the transmitter. Due to the different physical quantity requirements, the current transmitters on the market mainly include pressure transmitters, liquid level transmitters, temperature transmitters, temperature and humidity transmitters, differential pressure transmitters, soil moisture transmitters, and so on. In recent years, transmitter technology has been continuously upgraded both domestically and internationally, with a fundamental, strategic, and information-based trend, playing an important role in promoting industrial transformation and emerging industries.
