Document Type and Number:
Japanese Patent JPS5062673
Kind Code:
A
Abstract:
A marine torsiometer includes a pair of spaced collars clamped to a rotating propulsion shaft with a link affixed to the two collars to sense torsion in the shaft. The link includes two waist portions with strain gauges affixed thereto and connected in an electrical bridge configuration to cancel out the effects of bending and provide an electrical indication of torsion only. A transmitter is mounted on the link and converts the electrical indication to an FM radio frequency which is coupled to a stationary receiver through a rotary transformer. The power to the bridge circuit is also coupled through the rotary transformer.
