产品分类概述

TAMURA 提供多种多样的电流传感器以满足各种客户的不同需求：开环型（或线性）；闭环型（零磁通）；磁通门型（磁平衡）。

开环

L＊＊Series(＊＊ is Number)

In the open loop type current sensor, the magnetic core concentrates the magnetic flux generated by the measured current in the gap of the magnetic core where the Hall element is placed. The resultant low-level voltage output of the Hall element is voltage amplified to a higher voltage output level. The sensor output voltage is linearly proportional to the magnetic flux generated by the measured current.

闭环

S＊＊Series(＊＊ is Number)

For the closed loop type, the addition of a secondary winding to the magnetic core allows feedback current to be supplied in opposition to measured current to compensate or cancel the magnetic flux generated by the measured current. The output of the closed loop sensor is a current output proportional to the measured current divided by the number of secondary winding turns. The current output can be scaled with a load resistor to convert to voltage output.

磁通门

F＊＊Series(＊＊ is Number)

The flux-gate current sensor replaces the Hall element with a saturable reactor or ‘probe coil’ made of highly saturable material. The flux-gate utilizes a magnetic balance system to achieve high accuracy, temperature stable current output typically converted to a voltage output with an internal high precision resistor.
