Product Details

High-precision 3D Electronic Compass Veneer (plane Calibration)


Introduction

ER-EC31 High-precision 3D Electronic Compass Veneer (plane Calibration) is a high-precision 3D electronic compass that uses a 2D planar calibration algorithm. Calibration eliminates the need for three-dimensional attitude tilting, and the calibration process is completed by simply rotating the plane one turn. Using the hard magnetic and soft magnetic calibration algorithms of the US patent technology, the compass can achieve the best effect through the three-dimensional calibration method in the environment with magnetic interference. ER-EC31B integrates the three-axis fluxgate sensor and is real-time through the central processing unit. Solving heading and using a three-axis accelerometer to compensate for heading over a wide range of tilt angles, ensuring that the compass provides high-precision heading data at tilt angles up to ±85°. The electronic compass integrates high-precision MCU control and diversified output modes. The standard interface includes RS232/RS485/TTL interfaces, and other communication interfaces can be customized.

ER-EC31B is small in size, low in power consumption, and can be applied in many fields such as antenna stabilization, vehicle and system integration. High shock resistance and high reliability also make the compass work in extremely harsh environments, which is more suitable for today's small Chemical military high precision measurement integrated control system.
