Horizontal directional drilling technology completes the task of laying underground pipelines without destroying the surface environment. However, the practical application of this technology faces the challenge of accurately determining the drilling direction in complex underground environments.
As an instrument that can accurately measure the true north direction, the north finder provides an effective solution to the problem of determining the direction of horizontal directional drilling.
Take the ER-MNS-09 north finder as an example. It is a cylindrical north finder developed specifically for drilling. It is not restricted by the external environment and is not interfered by the magnetic field. It can provide azimuth and attitude information by itself. It can be used in machines such as HDD tools, gyro tools and underground tunneling machines to reduce measurement errors.
Unique shape, flexible installation The cylindrical shape is 120mm in length and only 30mm in diameter, and the weight is ≤150g. It can be installed in the probe behind the drill bit. High-accuracy North Seeking The north-seeking accuracy can reach 0.25°secฯ(1ฯ), which can achieve high-precision directional measurement and meet the strict accuracy requirements of horizontal directional drilling. Measure azimuth and attitude angle (pitch, roll) independently. The measurement error of azimuth is controlled within a very small range, providing reliable guarantee for drilling construction. Self-alignment and attitude tracking function After startup, it can automatically initialize alignment and then automatically determine the true north direction. The north search time only takes 5 minutes. It can also track and provide attitude information. Adapt to harsh environment, stable and reliable It can resist strong impact and vibration. The working temperature range of the normal temperature version is 5°C~+55°C. The working temperature range of the high temperature version is 5°C~+125°C.
