Product Details

     

Introduction

 ER-EC37B is a high accuracy 3D digital compass of strip shape, its length is only 1.6cm, IP67 protection grade, suitable for many harsh environment such as drilling measurement. It adopts advanced hard iron and soft iron calibration algorithm, it can provide the 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 sensitive measurement system. Sealed complete item and signal board are available.

ER-EC37B integrated patented three-axis flux-gate technology. It calculates heading value in real-time by CUP, and perform heading value compensation in wide tilt range by using three-axis accelerometer. It is high performance and excellent stability militarily level compass sensor. Its volume is small, power consumption is low. It could widely used in many application such as antenna installation, vehicle and integrated system, and so on.
