A voltage sensor is a sensor that can sense the voltage being measured and convert it into a usable output signal. In various detection and control systems, it is often necessary to track and acquire rapidly changing AC and DC voltage signals, and to perform spectral analysis on complex voltage waveforms. Its function is to automatically detect voltage, enabling us to control and display the voltage of equipment or systems, and to take automatic protection measures such as overvoltage and undervoltage when necessary.
A voltage sensor is a sensor that can sense the voltage being measured (depending on the model) and convert the obtained voltage into DC current or DC voltage within a certain time period (depending on the material and usage method), and output an isolated analog or digital signal. It is mainly used to measure voltage or current signals with severe waveform distortion in power grids, and can also measure non-sinusoidal waveforms such as square waves and triangular waves.
Compared with traditional current transformers and shunts, voltage sensors have advantages such as high accuracy, fast response, good linearity, wide bandwidth, strong overload capacity, and no loss of measurement energy. They have been widely used in many fields such as power, electronics, inverters, switching power supplies, and AC variable frequency speed control.
Installation method:
(1) Circuit board pin soldering installation: The sensor is soldered onto the circuit board as a component. Its advantages are small size, light weight, space saving and easy installation.
(2) Screw-fastened installation: The sensor is screwed onto the bottom of the chassis or a fixed position, and external connections are made via various terminal wires. Its advantages are that it is sturdy, convenient, and easy to disassemble.
(3) Rail mounting: The sensor has a standard 35mm wide dovetail groove at the bottom for snap-on mounting. Its advantages are convenience, versatility, and suitability for field installation.
