OXYGEN SENSOR WITH RESIDUAL LIFE INDICATOR |
摘要 |
A residual life indicator for a portable long life oxygen sensor. A circuit of the sensor includes a sensor electrode and counter electrode connected through a resistor network and a voltmeter calibrated to oxygen partial pressure. An electrolyte also connects the electrodes. A coulometer and temperature compensated resistor network is included in the sensor circuitry and provides visual indication of life expectancy. |
