PIEZO TORQUE TUBE STRAIN GAUGE WITH PIEZO GENERATOR

摘要

A torque tube sensor to measure torque on a torque tube includes a sensorbody including at least a first body section and a second body section and oneor morestrain gauges including a first strain gauge disposed in the first bodysection, the firststrain gauge including a piezo-electric layer that produces a voltage based ondeflection of the layer. The sensor also includes a first transmitter thatincludes acontroller, a power generator and wireless transmitter, wherein the controllerreceivesthe voltage produced by the piezo-electric layer.
