Detailed Product Description

ER-EC08B High Accuracy 3D Digital Compass



ER-EC08B High Accuracy 3D Digital Compass is a high accuracy 3D compass sensor. Integrated the digital signal RS232 and 4-20mA output. With IP67 water-proof grade, more suitable for drilling measurement. it uses advanced hard iron and soft iron calibration algorithm, it can still provide the high precision heading information in the roll angle 360 to any tools surface. It has the characteristics of small and low power consumption, and more suited to today's miniaturization sensitive measurement system.

ER-EC08B 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-EC08B is small in size and low in power consumption, and is widely used in many fields such as antenna stabilization, vehicle and system integration.
