The voltage sensor is a device that converts the measured AC voltage, DC voltage, and pulse voltage into a DC voltage or DC current in a linear ratio and isolates the output analog signal or digital signal.
How to use voltage sensor----Measurement of voltage sensor
(1) Contact measurement: Both the measurement quantity must be connected to the sensor, and the sensor is serially connected to the primary side circuit. Voltage sensors, some small current sensors and 5A transmitters are all contact measurement.
(2) Non-contact measurement: the amount to be measured does not need to be broken, and the primary circuit can pass through the sensor.
