MULTIPLE VIBRATORY ROTATION SENSORS WITH MULTIPLEXED ELECTRONICS

摘要

A vibratory rotation sensor comprising a resonator, a resonator housing and a method for controlling and reading out signals from the sensor is packaged in groups of three, along with a single control and read-out electronics circuit which is either time division multiplexed, frequency multiplexed or a combination of both for the three sensors. This multiple sensor package is compact, lightweight, rugged and well suited for use as an inertial measurement instrument in several subterranean environments such as in mining, tunneling, and oil and gas drilling applications.
