Abstract
A sensor system includes a plurality of strain gauges and a passive compensation circuit. The plurality of strain gauges are configured to provide an output voltage indicative of a sensed pressure using an input voltage. The passive compensation circuit that includes a span resistor, first and second compensation resistors, and a zero offset resistor. The span resistor is connected between an input voltage and the pressure sensor and is configured to control a range of an output voltage for a pressure range of the pressure sensor. The first and second compensation resistors are operatively connected in parallel with the pressure sensor and are configured to control current provided to the pressure sensor. The zero offset resistor is operatively connected between the first and second compensation resistors and the pressure sensor and is configured to control a base value of the output voltage for zero pressure.
