대표청구항 ▼

The invention claimed is: 1. A pre-calibrated gas sensor, comprising: a cathode and an anode for outputting a current signal responsive to a sensed oxygen concentration, wherein the cathode and the anode are in communication with a liquid electrolyte solution; and a signal processing module in communication with the cathode and the anode and having a pre-calibration transfer function stored therein, wherein the signal processing module comprises a microcontroller and is configured to receive the current signal and to output a pre-calibrated signal representative of the sensed oxygen concentration based on the pre-calibration transfer function and a value of the received current signal, and wherein the pre-calibration transfer function comprises a gain function for compensating a time-dependent drift of the gas sensor caused by at least one of a reduction in ion concentration of the electrolyte solution and formation of precipitates on the anode. 2. The gas sensor of claim 1, further comprising a housing enclosing the cathode, the anode, and the signal processing module. 3. The gas sensor of claim 1, wherein the signal processing module is further configured to receive the pre-calibration transfer function from a host computer in communication therewith. 4. The gas sensor of claim 1, wherein the gain function comprises an initial gain constant and a drift compensation function having time as an independent variable. 5. The gas sensor of claim 1, wherein the signal processing module further comprises an analog-to digital (A/D) converter in communication with the microcontroller. 6. The gas sensor of claim 1, wherein the signal processing module further comprises a digital-to-analog (D/A) converter in communication with the microcontroller. 7. The gas sensor of claim 1, wherein the signal processing module further comprises a communication driver/receiver (D/R) module in communication with the microcontroller. 8. The gas sensor of claim 1, further comprising a display module in communication the signal processing module. 9. The gas sensor of claim 5, wherein the signal processing module further comprises a current-to-voltage (C/V) converter in communication with the A/D converter. 10. A system for pre-calibrating a gas sensor, comprising: a cathode and an anode for outputting a first current signal responsive to a sensed oxygen concentration in a first gas, wherein the cathode and the anode are in communication with a liquid electrolyte solution; a signal processing module in communication with the cathode and the anode, wherein the signal processing module comprises a microcontroller and is configured to receive the first current signal and to output a first digital code representative of the first current signal; and a host computer in communication with the signal processing module, wherein the host computer is configured to receive the first digital code and to determine a pre-calibration transfer function based on the first digital code and a time-dependent drift of the gas sensor caused by at least one of a reduction in ion concentration of the electrolyte solution and formation of precipitates on the anode. 11. The system of claim 10, further comprising a housing enclosing the cathode, the anode, and the signal processing module. 12. The gas sensor of claim 10, wherein the cathode and the anode are further for outputting a second current signal responsive to a sensed oxygen concentration in a second gas, wherein the signal processing module is further configured to receive the second current signal and to output a second digital code representative of the second current signal, and wherein the host computer is further configured to receive the second digital code and to determine the pre-calibration transfer function based thereon. 13. The system of claim 10, wherein the host computer is further configured to communicate the determined pre-calibration transfer function to the signal processing module for storage therein. 14. The system of claim 12, wherein the first gas is a span gas and the second gas is a zero gas.
