Due to the late start of research and development in the field of sensors in our country, compared with developed regions such as Europe and America, the overall technology is relatively backward, especially in some specific sensor fields where there is still a considerable gap. As one of the main follow-up development products of sensors, the import of transmitters is also natural. What are the classifications of imported transmitters?

*The basic principle of a transmitter is to convert the measured physical signal into an analyzable and processable standard electrical signal, which can be output to various devices. So it can be classified according to the measured physical quantity. Common types of imported transmitters include temperature and humidity transmitters, liquid level transmitters, electrical quantity transmitters, weight transmitters, flow transmitters, differential pressure transmitters, and pressure transmitters, etc.

Among the commonly used imported transmitters mentioned above, the electric quantity transmitter is quite special. It also has different types according to different indicators, such as AC current transmitter and AC voltage transmitter, active power transmitter and reactive power transmitter, electricity transmitter, frequency transmitter, temperature transmitter, DC current transmitter and DC voltage transmitter, etc.

In addition, transmitters have a basic characteristic that instrument errors vary in different operating environments. Therefore, the measurement error value of a transmitter generally has a range, which is called the accuracy level based on the size of the range. Accuracy level is an important indicator for measuring instruments, and the higher the accuracy, the higher the performance of the instrument.

The reason why imported transmitters are of higher quality than domestic market transmitters is that they have better instrument accuracy than domestic related products.
