Hangzhi

Shenzhen, China

Company Overview

Hangzhi (航智) is a Chinese manufacturer of high-precision current and voltage sensing, headquartered in Shenzhen. The company specialises in fluxgate-based closed-loop current transducers that bring metrology-grade accuracy — once the preserve of laboratory instruments — into industrial measurement, serving new-energy-vehicle test benches, battery production, fuel-cell systems and precision power analysers.

History

Hangzhi was founded by a team with deep magnetics and instrumentation experience, aiming to localise the zero-flux current-sensing technology long dominated by European makers. Through iterative development of magnetic cores, fluxgate electronics and compensation loops, the company built a product family whose accuracy, drift and bandwidth now stand comparison with imported alternatives, at a cost structure suited to volume industrial use.

Strengths

The core strength is precision fluxgate engineering: very low offset and temperature drift, high linearity and wide bandwidth retained across large measurement ranges. Local engineering support allows fast customisation of window size, primary-bar geometry, output scaling and mounting, and units are delivered with calibration certificates.

Product Portfolio

• High-precision fluxgate current transducers (tens of amperes to kA-class)
• Wideband current transducers for switching-loss and double-pulse measurement
• Precision voltage sensors for isolated DC-bus measurement
• OEM and custom sensing modules for test-system integrators
