Introduction

Magnetic gradient sensor is included two three-axis fluxgate sensor close fixed on the same stable support beam,  data acquisition circuit, communication circuit and other components.

Measurement Principle:

Use two high performance magnetic sensors at a certain distance to form the three component horizontal gradient measurement.

Working Principle

Put two three component fluxgate sensors on the horizontal base in parallel, and the fluxgate sensor spacing is the baseline distance of the gradient sensor. After 6-channel 24 bit AD conversion, the test data is stored in the internal memory module, and the data can be uploaded synchronously through RS485 interface or CAN bus.

The measuring principle and working principle of magnetic tensor sensor are similar to that of magnetic gradient sensor. The difference is that the former is required no less than 4 sensors, which are built by group array. The structure of array includes cross aluminum alloy frame or cuboid three-dimensional frame.

Application

Geophysical exploration, underwater magnetic detection, urban underground pipeline positioning, etc..

Note: magnetic gradient index is similar to magnetic tensor index
