2000A current sensor

1. The Hall Effect: Translating Current in Magnetic Fields Hall current sensors operate on the Hall Effect—when current flows through a conductor perpendicular to a magnetic field, charge carriers deflect under Lorentz force, generating a voltage (VH) proportional to magnetic flux density.   The formula is:VH = (RH × I × B) / d(RH: Hall coefficient; I: Current; B: Magnetic field; d: Material thickness). This enables non-contact current measurement, eliminating contact loss and high-voltage risks in EVs and smart grids.   2. Precision Evolution: From Open-Loop to Closed-Loop Two core technologies dominate: Open-Loop (e.g., Token TKC Series) Simple structure, cost-effective (40% savings) Ideal for industrial drives and UPS Closed-Loop (e.g., Token TBC Series) Compensation coils generate counter-magnetic fields to maintain "zero flux" Accuracy up to 0.1%, temperature drift <±10ppm/°C, critical for EV motor contro Closed-loop’s anti-interference capability shines in 200kHz SiC switching noise environments. Combined with electromagnetic shielding (Faraday cages), it suppresses >60dB common-mode noise.   3.

  Hall current sensors have become indispensable in modern electrical systems, offering non-intrusive current measurement solutions. However, one of their most impressive capabilities is their ability to maintain accuracy in environments plagued by high-frequency interference. This blog post explores the sophisticated techniques these sensors employ to combat electrical noise and deliver reliable measurements. The High-Frequency Interference Challenge Electrical systems today face numerous sources of high-frequency noise: Switch-mode power supplies (kHz to MHz range) ·Variable frequency drives ·RF transmission sources ·Power line communication signals ·Lightning-induced transients  Magnetic Shielding Advanced Hall sensors incorporate: Mu-metal enclosures that divert interfering magnetic fields Layered shielding that addresses different frequency bands Grounded shields that block capacitive coupling  Advanced Packaging Innovations include: Guard rings around sensitive components Optimized PCB layouts that minimize loop areas Real-World Performance Properly designed Hall sensors can maintain: Better than 1% accuracy in environments Immunity to fast transients exceeding 2.5kV/μs Through a combination of physical design, clever circuitry, and digital processing, Hall current sensors achieve remarkable immunity to high-frequency interference. This makes them suitable for demanding applications from industrial motor control to aerospace systems where electrical noise would overwhelm conventional measurement techniques. Engineers can confidently specify these sensors knowing they'll deliver accurate current measurements regardless of the challenging electromagnetic environment they operate in.
