What is a gyroscope used for?

 

A gyroscope is a sensor used to measure angular velocity. Its core function is to sense the rotational motion and attitude changes of an object. It can be applied to various fields that require navigation, positioning or stable control.

ER-MG-057, as a high-performance single-axis MEMS gyroscope (angular velocity sensor), has become an ideal choice for many professional fields due to its excellent performance and reliable design.

HDD technology breakthrough! North seeker helps with orientation in trenchless construction

 

As the core technology of trenchless pipeline laying, HDD technology places extremely high demands on the direction control of the drill bit. The precise control of the drilling trajectory depends on high-performance directional measurement equipment. With its unique technical advantages, the ER-MNS-09 north seeker has become a key equipment for improving construction efficiency and accuracy in HDD operations.

Core challenges and directional requirements of HDD construction

HDD construction requires the completion of pilot hole drilling, hole expansion, and pipeline pullback processes underground. Directional equipment needs to meet the requirements of narrow space adaptation, high-precision orientation, resistance to complex environmental interference and impact vibration, and adaptation to extreme working conditions.

ER-MNS-09’s technical advantages and HDD compatibility

**High-precision measurement to ensure trajectory control**

The azimuth accuracy can reach 0.25°, and the attitude accuracy is ≤0.2°. With a data update rate of 100Hz, it supports stable operation in the inclination range of -85~85°. The operator can adjust the drill bit trajectory in time based on the measurement data to meet the strict restrictions on trajectory deviation in HDD construction;

**Ultimately compact design, embedded in the core space of the probe tube**

The HDD guided probe pipe needs to be embedded in the front end of the drill pipe, and the size and weight of the equipment are limited. The ER-MNS-09 north seeker has a diameter of only 30mm, a length of 120mm, and a weight of ≤150g. It can be seamlessly integrated into the probe pipe or guide head at the front of the drilling equipment, and is suitable for mainstream drilling equipment.

**Autonomous north finding and anti-magnetic interference**

Adopting a high-precision MEMS gyroscope that can self-find north, the initial alignment is completed in 5 minutes, completely free from dependence on the geomagnetic field, and can stably output the true north azimuth, pitch angle and roll angle information in strong interference environments such as underground mines, metal pipelines or strong electromagnetic environments.

All-solid-state design: no mechanical rotating parts, excellent anti-impact and vibration ability, meeting the reliability requirements under severe vibration conditions during drilling.

**Wide temperature adaptability to cope with extreme working conditions**

Full temperature calibration compensation: The normal temperature version supports an operating temperature of 5~+55°C, and the high temperature version supports 5~125°C. It can withstand strong vibration and shock environments to ensure long-term reliability in deep wells, mud environments or high shock conditions.

Precise application of high-performance dynamic FOG north seeker in mining and oil exploration

 

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.
