Yesterday, the 23rd Taiyuan Coal (Energy) Industry Technology and Equipment Exhibition was successfully held. The MEMS north seekers and fiber optic north seekers promoted by ERICCO became the focus of the event. During the exhibition, multiple groups of professional customers stopped for consultation and reached strategic cooperation intentions, which fully demonstrated the technology leadership and market recognition of the North Seeker in the field of coal mining.
Different from the shortcomings of traditional magnetic compasses that are susceptible to interference from underground metal ore bodies and electromagnetic equipment, the north seeker uses inertial measurement technology and uses a full temperature range compensation algorithm to eliminate the influence of temperature drift. With an industrial-grade anti-vibration design, it can still output data stably under complex working conditions of dust, moisture, and vibration, reducing the risk of equipment downtime caused by positioning failure.
ER-MNS-04: Extreme size, supports OEM customization
The size of the shell is only 40×40×42mm, the weight is 80g, and the inner body is reduced to 27×26×3mm (40g). It has strong OEM compatibility and supports customized integration. It does not need to rely on specific interfaces (such as 15-pin plugs), reducing the cost of transformation.
The heading accuracy is as high as 0.25°secψ (1σ), and the attitude accuracy is ≤0.2°, which meets the stringent requirements of drilling orientation, equipment positioning and other scenarios. In deep wells or tunnels without GPS signals, it provides heading and attitude information for unmanned mining vehicles or inspection robots to ensure their accurate movement in complex paths.
ER-MNS-06: Miniaturized design, easy to integrate
The size is only 38.6×44.8×25.5mm and the weight is 70g. The heading accuracy can reach 0.25°secψ (1σ), the 5-minute fast north-seeking capability and 100Hz data update rate significantly improve the real-time performance of dynamic operations. Supports attitude calibration of tunneling machines and coal mining machines.
Provides RS-422 communication interface and 3.3V power supply, which is convenient for seamless connection with mining control systems or automation platforms.
ER-MNS-09: Heterosexual housing, drilled for adaptation
The size is only 120mm × Φ30mm and the weight is ≤150g. It is one of the smallest diameter MEMS north seekers on the market. The cylindrical design is easy to integrate into the drill pipe and downhole drilling equipment, and adapts to the narrow space of the mine.
30 seconds fast alignment (accuracy 1°) and 90 seconds precise alignment (accuracy 0.5°) significantly shorten the operation preparation time and improve drilling efficiency.
The azimuth measurement range is 0°~360° and the inclination range is -85°~85°, providing precise trajectory control for drilling under complex geological conditions. 5~125℃ full temperature calibration compensation, anti-strong magnetic and metal interference.
In the coal industry, this product is mainly used in:
Precise orientation of tunnels: In tunnel boring machines, azimuth pointing is used to reduce tunnel penetration errors and construction risks and costs;
Geological exploration assistance: In complex coalbed methane mining, directional drilling trajectory control is assisted to improve resource recovery;
Unmanned equipment navigation: Provide initial azimuth benchmarks for unmanned mining trucks and inspection robots to improve the reliability of autonomous navigation.
Customer feedback and industry recognition
During the exhibition, customer consultations mainly focused on technical parameters, cost-effectiveness and after-sales service. The technical director of a large coal company said: "Traditional magnetic compasses are often interfered with underground, and your company's north seeker is exactly what we need." In addition, some customers showed great interest in modular design, believing that it is easy to integrate with existing comprehensive mining equipment and can accelerate the process of intelligent transformation.
We sincerely invite you to visit booths 618-619 in Hall S1 to experience innovative technologies and explore cooperation opportunities!
