Claim:
1. A sensor system with performance compensation testing capability, comprising: a sensor device; a resistance bridge circuit disposed on the sensor device and including an excitation terminal, a circuit common terminal, and two output terminals, the resistance bridge circuit configured, upon being energized, to supply a bridge output voltage across the two output terminals; a signal conditioning circuit electrically coupled to the excitation terminal, the circuit common terminal, and the two output terminals, the signal conditioning circuit configured to supply a sensor output signal representative of the bridge output voltage; a first test connector electrically coupled to one of the two output terminals, the first test connector configured to be coupled to an impedance test device; and a second test connector electrically coupled to the circuit common terminal so that the second test connector is directly coupled to the signal conditioning circuit, the second test connector configured to be coupled to the impedance test device to vary an input to the signal conditioning circuit for simultaneous derivation of a first temperature shift of the resistance bridge circuit and a second temperature shift of the signal conditioning circuit.
