Magnetic drill head tracking

On behalf of and in partnership with Brunschwiler AG, Mems AG has developed a tracking system for the controlled horizontal drilling method. Determination of the position, direction and roll angle of the drill head.

With this tracking system, the magnetic field of a permanent magnet integrated into the drill head is measured from above ground with a sensor platform and the position, direction and roll angle of the drill head are determined.

The measurement data is then transferred wirelessly to a rugged tablet and is continuously displayed on the screen. The controlled dry drilling method is particularly advantageous for domestic connections. The roll angle of the asymmetrically angled drill bit determines the direction of drilling and the flexible drill rod allows for a minimal drilling radius of ten meters. The axial propulsion is done with the hammer drill that is powered by compressed air.

Mems AG has a prototype of a magnetic drill head for use in Ditch Witch Systems. Various field tests and trials at customers’ homes with a pilot series of drill head tracking devices have been successful.
