ABSTRACT:
An angular velocity sensor utilizing the Coriolis effect on a fluid jet employs a metal diaphragm impulse jet pump with no valves to reduce temperature sensitivity. The pump anvil, the nozzle block and the sensor plug may all be fabricated of the same material to further reduce temperature sensitivity. The thickness of the sensing elements is selected to reduce temperature sensitivity still further.
