To measure the size of the process used, it uses a measuring device called a sensor (the part that is directly connected to the measured media), where the transmitter converts the signal received from the sensor into a standard signal. Depending on the amount to be converted, transmitters can be classified as temperature transmitters, high level transmitters, flow transmitters. The transmitter can be connected to various receivers such as signaling devices, recorders and regulators with standard input signals. Depending on the type of output signal, it can be distinguished, for example, an antenna transmitter signal and an electric transmitter.

The transmitter utility provides standard signals in the form of air signals or electrical signals from the measured process variables to other devices that you need, among others. Other equipment such as indicators, recorders that operate in the same signal standard, enable signal transmission over large, fast and safe distances, reducing operating and maintenance costs. Transmitter signal is a signal or signal given to a receiver such as a recorder, pointer in the form of a digital scale. The type of signal contained in the transmitter is.

Electric signal The standard size of this electrical signal is 4 mA - 20 mA, and the working scale of the voltage signal is around 1-5 DC, and there are also 0-10 DC. The types of transmitters in a device are known as two signal systems that can be used in transmitters, namely aerodynamic signals and electrical signals. Depending on the two systems, transmitters can be classified into two types, electric transmitters and pneumatic transmitters. In general, this transmitter system is the path of sending signals from the device to the console and from the console to the final regulator (control valve).
