Product Details

High Accuracy 3D Digital Compass


Introduction

ER-EC37B High Accuracy 3D Digital Compass is a high accuracy 3D digital compass of strip shape, its length isonly 1.6cm, IP67 protection grade, suitable for many harsh environment such as drillingmeasurement. It adopts advanced hard iron and soft iron calibration algorithm, it can providethe high-precision heading value output when both pitch and roll angle at any angle within 360.it is small and low power consumption, suitable for current miniaturization sensitivemeasurement system. Sealed complete item and signal board are available.

ER-EC37Bintegrated patented three-axis flux-gate technology. It calculatesheading value in real-time by CUP, and perform heading value compensation in wide tilt rangeby using three-axis accelerometer. It is high performance and excellent stability militarily levelcompass sensor. Its volume is small, power consumption is low. It could widely used in manyapplication such as antenna installation, vehicle and integrated system, and so on.
