Abstract

A downhole instrument includes an instrument housing, a sensor yoke rotatably mounted within the instrument housing, and an angular rate sensor carried by the sensor yoke. A first rotational stop is mounted to the instrument housing that defines a first rotational position of the sensor yoke. A second rotational stop mounted to the instrument housing defines a second rotational position of the sensor yoke that is rotationally spaced from the first rotational position. A differential screw may be connected to the second rotational stop that is adapted to adjust a position of the second rotational position. A torsion coupling may be coupled between the rotational driver and the sensor yoke, where the torsion coupling is energized by the motor that rotates the sensor yoke with a returning force that resists movement of the sensor yoke away from the first rotational stop.
