Voltage Sensor

The voltage sensor is a device that converts the measured AC voltage and DC voltage into a linear proportional output DC voltage or DC current, and then isolates and outputs an analog signal or a digital signal. Voltage sensors are used to measure voltage signals with severe waveform distortion in the power grid, and can also measure non-sinusoidal waveforms such as square waves and triangle waves.
From the measurement principle, it can be devided to Hall effect voltage sensor, photoelectric isolation voltage sensor, electrical isolation voltage sensor, voltage transformer (electromagnetic induction principle) and so on. According to the voltage polarity, it is divided into DC voltage sensor and AC voltage sensor.
The AC voltage sensor is widely used in electrical installations and automatic control in power, post and telecommunications, petroleum, coal, metallurgy, railway, municipal and other departments And scheduling system. AC voltage transducers are divided into single-phase voltage sensor or 3 phase voltage transducers.
The DC voltage sensor is also widely used in power, remote monitoring, instrumentation, medical equipment, industrial automatic control, that require power isolation measurement and control industry.
