It is an important electrical equipment, widely used in industrial automation and power systems. The function of this transmitter is to convert the measured three-phase AC voltage into a linear proportional DC current or DC voltage. In the modern industrial automation environment, the application of transmitters has been widely popularized.

Three-phase AC voltage transmitter is usually composed of voltage transformer, bridge rectifier circuit, filter circuit and output amplifier circuit. The AC voltage is first depressurized by the voltage transformer, then rectified by the bridge rectifier circuit for full wave, and finally through the filter circuit to obtain smooth direct current. This direct current, as the output of the transmitter, can reflect the size of the input AC voltage, and has a good linearity.

In the process of use, if you find that the signal of the AC voltage transmitter is not correct, you must first check its output current signal to eliminate the possibility of failure. Sometimes, the problem may be due to interference caused by too high AC voltage at the output of the AC voltage transmitter. In this case, consider using a signal isolator to solve the problem. The signal isolator can effectively isolate all kinds of interference to ensure the accuracy and stability of signal transmission.
