A sensor gimbal system employs one sensor gimbal on which a sensor is mounted. The sensor gimbal is configured to orient a sensitive axis of the sensor with respect to a survey instrument. A sensor motor assembly is configured to rotate the sensor gimbal between a first hard stops and a second hard stop. A dowel pin extends from the mating bevel gear to engage the hard stops. A flex circuit has a flex cable from a sensor PCB, on which the sensor is mounted, to an electronic circuit board.

Survey instrument

A drill hole logging system () incorporates a computing system () at the surface and a deployment mechanism () for conveying a logging tool () configured to measure one or more geophysical parameters into a drill hole (). A transmission means () communicates commands and data representing the geophysical parameters between the surface computing system and the logging tool. A borehole caliper () is employed to profile the inside of the borehole.
