How to Determine the Quality of Hall Effect Current Sensors

1. Visual Inspection In simple terms: A Hall effect current sensor is a “magnetic-electric” converter that can linearly convert the strength of a magnetic field into a voltage signal. Check the sensor casing for burn marks, cracks, deformation, or pin corrosion and other obvious physical damage. Overheating often causes discoloration or bulging of the casing. … Read more
