1. Advantages:

High accuracy: the accuracy in the working temperature zone is better than 1%, the accuracy is suitable for any waveform measurement; Hall switch equipment has no contact, no wear, clear output waveform, no jitter, no bounce, high position repetition accuracy (up to μm).

The measurement scale is wide: current measurement can reach 50KA, voltage measurement can reach 6400V.

Wide bandwidth: the rise time of the high-bandwidth current sensor can be less than 1μs; However, the bandwidth of the voltage sensor is narrow, generally within 15kHz, the rise time of the high-voltage voltage sensor of 6400Vrms is about 500uS, and the bandwidth is about 700Hz.

Strong structure, small size, light weight, long life, convenient equipment, low power consumption, high frequency (up to 1MHZ), sensation resistance, not afraid of dust, oil, water vapor and salt spray pollution or corrosion.

2. Defects:

The interchangeability is relatively poor, the signal changes with the temperature, the nonlinear output, and the nonlinear and temperature proofreading have to be carried out by the single chip computer.

Due to these characteristics of Hall sensors, Hall sensors are widely used in frequency conversion speed regulation equipment, inverter equipment, UPS power supplies, communication power supplies, welding machines, electric locomotives, substations, CNC machine tools, electroplating, microcomputer monitoring, power grid monitoring and other facilities that need to block detection current, as well as new solar energy, wind energy and subway track signals, automotive electronics and other fields.
