  • Method and device for the measurement of the drift of a borchole
    Patent number: 6845563
    Abstract: A device and a method for the measurement of the angle of drift of a borehole that extends from the surface of the ground downwardly into the earth. The device comprises a generally hollow protective exterior casing, a microprocessor control; and, a sensor pack. At least the microprocessor control and the sensor pack are received and contained within the exterior casing. The sensor pack includes one or more accelerometers mounted upon a sensor chassis that is positioned within the casing and situated generally parallel to its longitudinal axis. The sensor chassis has one or more mounting surfaces for receiving and securing the one or more accelerometers to the sensor chassis. The mounting surfaces are configured such that the one or more accelerometers when secured to the chassis are held and retained at an inclined angle relative to the longitudinal axis of the exterior casing and the device.
