The Bell-Boeing engineers, in working up a scheme by which to power the shaft-mounted electronics and retrieve strain gauge
signals from the spinning rotors, elected to use the slip-ring system that would be in place on the Osprey anyway.
A bolt with integrated strain gauge
was used that was calibrated to a maximum of 30 kN.
10] - initial resistance of a strain gauge

If strain gauges
are used, it is possible to achieve good results with a small amount of measurement points, and the measurement equipment can be set so individual loading components can be scanned directly during flight.
Both the strain gauge
and the measuring circuit are, in the physical sense, passive components.
Therefore, a sensor with strain gauges
was designed for the purpose of biaxial force measurement.
Figure 4 presents comparison of torque versus time behavior derived from strain gauge
signals during calibration on TSHB apparatus.
Louis Statham, a physicist at the Curtiss-Wright Airplane Company, subsequently developed an unbonded strain gauge
and pioneered a transducer manufacturing company using this technology.
Moving a strain gauge
even slightly on the board may yield drastically different results.
Typical examples are mechanical systems, such as the micrometer screw and precisely machined contact points that are integrated within proving ring transducers, and electrical voltage-ratio measuring instruments supplied by customers for connection to strain gauge
PHI] is angle of rotation of corresponding strain gauge
