The energy supply and signal transmission requires the use of slip-rings or contactless forms of transmission, such as rotary transformers or telemetry systems.
能源供应和信号传输需要滑环或接触传播的形式，如旋转变压器或遥测系统的使用。

This material is suitable for low power signal transmission transformers (such as ADSL transformers), and can reduce harmonic distortion and improve transmission speed.
这种材料适用于低功率信号传输变压器（如ADSL 变压器），可以降低变压器谐波失真，提高传输速率。

The sensor uses two revolving transformers to transfer the electrical source and the signal without contacting. It also implements remote monitoring tests through the field bus technology.
