  • Abstract
    This paper presents several amplifier circuits for use with strain gauges. The circuits are inherently linear, produce four times the output of the standard Wheatstone bridge, and can easily be extended to accommodate multiple strain gauges. The implementation platform is the low-cost operational amplifier instead of the more expensive instrumentation amplifier, and circuit functionality has been verified using PSPICE simulations, and laboratory tests.
