ERICCO INERTIAL TECHNOLOGY ER-MNS-06A Low cost MEMS north seeker for Heading machine Adopt the latest MEMS gyro technology, compact size; Adopt three-axis MEMS gyro, three-axis MEMS plus strapdown inertial measurement technology; All-solid-state design, excellent anti-shock and anti-vibration ability, and resistant to harsh environment; With self-seeking north function, not affected by magnetic field; Introduction ER-MNS-06A is an ultra-low-cost MEMS north seeker mainly used for tunnel boring machines. It adopts the latest MEMS gyro technology and is a precision measurement and orientation device that breaks through the traditional volume advantage. It has the characteristics of small size, light weight, and low power consumption. The compact size and lightweight structure greatly reduce the requirements for installation space and can be seamlessly embedded in narrow space scenes. It is mainly used in mining engineering, underground tunneling, construction and other fields. It can be integrated in engineering machinery such as tunnel boring machines and mining equipment, as well as various fields that require orientation. Different from traditional magnetic compasses, the north finder is completely unaffected by the geomagnetic field. It adopts three-axis MEMS gyroscope and three-axis MEMS plus meter strapdown inertial measurement technology. It does not require external reference signals to solve the carrier attitude and north azimuth. It can still maintain stable output in strong magnetic environments, high-latitude geomagnetic anomaly areas or electromagnetic pulse environments. Technical Features 1. Adopt the latest MEMS gyro technology, the volume is extremely reduced, the size is only 38.6×44.8×25.5mm, easy to integrate; 2. Adopt the latest three-axis MEMS gyro, three-axis MEMS accelerometer strapdown inertial measurement technology; 3. With self-seeking function; 4. Not affected by magnetic field; 5. Light weight, low power consumption; 6. 5°C to 55°C temperature compensation; Applications Direction of advanced mining/drilling equipment Excavation operations in underground tunnels of coal mines, metal mines, etc., suitable for large equipment such as cantilever tunneling machines and continuous coal miners Orientation and attitude measurement of transportation equipment such as mining AGV in underground tunnels Precision platform attitude measurement and control Bridge, high-rise building, high tower, dam monitoring Whatsapp/Wechat/Mob:8613992884879 Websit : www.ericcointernational.com E-mail : ericco001@ericcointernat
