2024-01-02

Jiangsu MultiDimension Technology Co., Ltd. (MDT), a magnetic sensor manufacturer specializing in Tunnel Magnetic Resistance (TMR) technology, has launched a new 3pT level compact high-precision low noise linear magnetic sensor - TMR8503- based on high sensitivity TMR technology. The sensor integrates a magnetic field feedback coil and a signal conditioning circuit, which can achieve low noise of 3-5 pT/Hz1/2 @ 1Hz, as well as 0.05% linearity, 40 PPM sensitivity temperature drift, and 500 kHz bandwidth. It can achieve high-precision, fast, and real-time measurement of weak magnetic fields.
