Product Details

product description

The ER-EC50B is a high-precision 3D compass veneer with a long strip volume and a width of only 1.6CM, which is more suitable for drilling measurement. It uses advanced hard iron and soft iron calibration algorithms to make it roll tool at any angle of 360°. The surface still provides high-precision heading information. It has the characteristics of small size and low power consumption, and is more suitable for today's miniaturized sensitive measurement systems.

ER-EC50B integrates patented three-axis fluxgate technology, real-time solution of heading data through central processing unit, and three-axis accelerometer for heading compensation of a wide range of tilt angles. It is a high-performance, high-stability military-grade product. The ER-EC50B is small in size and low in power consumption, and is widely used in many fields such as antenna stabilization, vehicle and system integration.
