North Seeker for Hydraulic Supports in Underground Coal Mines
Introduction
ER-MNS-10A MEMS North Seeker is a special north seeker for hydraulic supports in coal mines. It adopts the latest MEMS gyro technology, with a height of only 14mm and a total product weight of 40g. It has the world's thinnest and lightest disruptive design, breaking through the volume and weight limitations of traditional equipment. The flat structure can be easily applied to various occasions with strict requirements on height and weight.
Using the latest three-axis MEMS gyro and three-axis MEMS plus meter strapdown inertial measurement technology, the angular velocity and acceleration are solved to achieve fast and stable measurement of attitude control and true north reference.
It has excellent temperature adaptability and supports compensation in a wide temperature range of 5°C to 55°C. Stable output in different working environments..
