ABSTRACT:
In a mechanical to electrical transducer, a plurality of strain gauges are mounted either on a diaphragm or on a flexure spring mechanically coupled to the diaphragm. The diaphragm is mounted on a clamping ring, and the strain gauges are disposed at different distances from the clamping ring. In order to equalize the heat transfer of the strain gauges with respect to the clamping ring, the areas of the strain gauges may be varied, the spacings of the conductors of the strain gauges may be varied, the relative positioning of the strain gauges may be controlled, the width of various portions of the flexure spring may be varied, or slots may be provided adjacent certain strain gauges in the flexure spring.
