Introduction

Ran Shi is an inventor based in Zhangjiagang, China, and is associated with Multidimension Technology Co., Ltd. His patent work includes a current sensor designed to measure across high and low current ranges.

Latest Patents

Shi is credited with 1 patent, titled “Current Sensor with High and Low Current Ranges.” The invention uses an input module with a differential copper bar and a current-shunting copper bar connected in parallel. As current flows through these bars, it generates a magnetic field detected by separate high- and low-current modules.

The high-current module places two magnetic sensing units in a gap within the input module, while the low-current module positions two sensing units outside it. Each pair differentially senses the magnetic field and produces an output signal. This arrangement is intended to expand the sensor’s current measurement range.

Career Highlights

Shi’s listed invention addresses current sensing across different measurement ranges through a design that combines parallel copper bars with distinct magnetic detection modules. He is associated with Multidimension Technology Co., Ltd.
