GMR-16 Miniature Weak Magnetic Field Sensor Array
sketch:
Koley Technology Co., Ltd. has years of experience in magnetic field testing and has launched the GMR-16 micro weak magnetic field sensor array. The standard version can synchronously collect data from 2-16 COLIY micro weak magnetic field sensors. The maximum collection speed per channel is 50 sps. Suitable for synchronous testing of various spatially varying magnetic fields, simultaneous testing of multiple weak magnets, rapid scanning of the same weak magnetic field, and distribution testing of gradient magnetic fields.
The micro weak magnetic field sensor adopts a three-dimensional structure with an orthogonality error of less than 1 degree, and can simultaneously measure the magnetic fields of XYZ. The minimum volume of the sensor is 5x5x3mm, with a magnetic field resolution of 10nT (output rate of 3ps), a range of up to 500 μ T, and a linearity of 0.1%. Good zero stability, with a typical zero drift of only 3nT/degree.
The data collected by the micro weak magnetic field sensor array GMR-16 is directly imported into the computer through USB 2.0. The standard product range is 2-16 channels, but it can also be customized according to user needs, with a maximum of 128 channels synchronized to meet customers' higher demands.
The micro weak magnetic field sensor array GMR-16 has the advantages of high accuracy, high stability, high resolution, miniaturization, digitization, and intelligence. With the continuous development of science and technology and the emergence of new materials and processes, the application scope of this system will continue to expand.
