ABSTRACT:
A strain gage sensor having improved operational aspects and lower production costs. The strain gage sensor includes two active resistors, two passive resistors, and a structure for minimizing strain experienced by the two passive resistors. The active and passive resistors are attached in a Wheatstone bridge configuration and are Piezoresistors. The active resistors and the strain minimizing structures are mounted on the backing plate. The backing plate or the strain minimizing structure includes alumina ceramic substrate. A voltage to current converter circuit is attached to the active and passive resistors and mounted to the backing plate. Multiple Wheatstone bridge circuits or multiple Wheatstone bridge circuits with voltage to current converter circuits are manufactured on a single backing plate and separated prior to use.
