Abstract
A rate detection system (10) uses a balanced resonant sensor (12) having first and second tines (14,16) interconnected with a mounting pad (20). A sensing circuit (50) including a tunnel effect displacement sensor (38) having a first probe (40) connected to the mounting pad (20) and a second probe (42) connected to a reference pad (32) detects an output signal having a Coriolis component. A feedback circuit provides a compensation signal to the balanced resonant sensor (12).
