Abstract
A sensor system with performance compensation testing capability includes a sensor device, a resistance bridge, a signal conditioning circuit, a first test connector, and a second test connector. The resistance bridge circuit is disposed on the sensor device and includes an excitation terminal, a circuit common terminal, and two output terminals, and is configured, upon being energized, to supply a bridge output voltage across the two output terminals. The signal conditioning circuit is electrically coupled to the excitation terminal, the circuit common terminal, and the two output terminals, and is configured to supply a sensor output signal representative of bridge output voltage. The first test connector is electrically coupled to one of the two output terminals and is configured to be coupled to an impedance test device. The second test connector is electrically coupled to the circuit common terminal and is configured to be coupled to the impedance test device.
