VOLTAGE SENSORS

Hall effect voltage sensors are based on closed loop current sensors. The primary circuit of the sensor has a primary resistor and a multi-turn coil, which creates a large number of ampere-turns to increase the primary inductance. For such devices, the set of measured voltages covers the widest range, which depends on the properties of the primary winding and the resistance of the primary circuit resistor. Voltage measurement accuracy - fractions of a percent.
