The orientation accuracy of drilling equipment directly affects the efficiency and safety of logging drilling, tunnel excavation, and ore body positioning. During underground drilling operations, the vibration and attitude changes of the drilling rig are frequent, and traditional mechanical gyroscopes or magnetic compasses are difficult to work stably.
ER-FNS-01D high-performance dynamic FOG north seeker can achieve real-time accurate north seeking and attitude following in a vibrating environment. The north seeking accuracy can reach 0.5°, and the attitude measurement accuracy can reach 0.03° (1σ). Dynamic north-seeking technology can provide the true north direction of the carrier in real time. The working latitude of 65°N-65°S covers major mining areas and oil and gas fields around the world, ensuring that the drilling rig can still accurately control the drilling direction even when tilted or vibrating.
The compact size of 100×100×75mm and the lightweight design of 1kg make it easy to integrate into drilling equipment. Its core technical advantages are precisely targeted at complex working conditions:
Fast and precise dual modes: Supports 30-second fast alignment (azimuth accuracy 1°) and 90-second precise alignment (azimuth accuracy 0.5°), significantly shortening the equipment startup time. It can quickly establish the north reference after the drilling rig is in place. At the same time, its 20-minute accuracy retention capability allows the drilling rig to quickly resume operations after a short stop, reducing the time loss caused by repeated alignment.
Full environment adaptability: 5℃-55℃ full temperature range compensation technology adapts to the temperature difference between the deep mine and the field; there is humidity, dust and potential electromagnetic and metal interference in the mine, and the ER-FNS-01D is not affected by the magnetic field, which completely avoids the influence of the electromagnetic environment on the measurement results.
Strong vibration adaptability: The built-in shock absorber design can withstand 20Hz-2000Hz, 6.06g vibration environment, solving the problem of accuracy drift caused by vibration in dynamic operations of traditional north-seeking equipment.
Under the surface, whether it is coal mining, tunnel penetration or geological exploration, accurate azimuth and orientation technology has always been the core guarantee of engineering safety and efficiency. North seekers are playing an irreplaceable role in these fields with their high precision and strong anti-interference characteristics.
Taking the north seeker ER-MNS-05Mini as an example, let’s understand how the north seeker works.
**Underground excavation**
The underground environment is complex, and deviations in the tunnel direction may lead to major safety hazards. Traditional measurement tools are easily affected by metal equipment and electromagnetic interference.
The north seeking accuracy of this north seeker can reach 0.25°secψ(1σ)! It can provide more accurate azimuth, pitch angle, roll angle and other attitude information. It not only has extremely high stability, but also is not affected by external interference and can be used in magnetic mining areas.
The shield machine is susceptible to interference from geological conditions and mechanical vibration during excavation. The guidance system integrated with the north seeker can correct the attitude of the shield machine in real time.
**Geological Exploration**
In geological surveys or tunnels passing through complex strata, it is necessary to accurately measure the direction of rock strata, fault directions, etc. The north seeker can provide a high-precision direction reference and can be used in conjunction with geological radar detection to ensure the accuracy of measurement data.
**Extreme size, flexible installation**
The size of ER-MNS-05 Mini is 40*40*42 (mini version with shell)/27*26*34 (mini version without shell and baseboard), and the weight is <80g (mini version with shell)/ 40g (mini version without shell and baseboard).
**OEM Customization**
It takes only a few simple steps to connect the product to your system and obtain the geocaching data without the 15-pin plug provided by our company. The size and weight of our products are significantly reduced by removing the base plate housing.
