Abstract: A system for measuring temperature sensed by a resistance thermometer attached to a moving structure. Impedance of the resistance thermometer is coupled into an AC bridge and a variable resistor is also coupled into the bridge to balance the bridge when the thermometer changes in impedance due to temperature change. The resistance of the variable resistor is sensed by DC circuitry and a resultant DC signal proportional to temperature is thus provided.

Abstract: A process oxygen analyzer includes a process probe extendible into a flow of process combustion exhaust, the process probe having an oxygen sensor measurement cell. Measurement circuitry is coupled to the oxygen sensor measurement cell and configured to obtain a non-corrected indication of oxygen concentration relative to a combustion process based on an electrical characteristic of the oxygen sensor measurement cell. A controller is operably coupled to the measurement circuitry and is configured to obtain an indication of process pressure and selectively provide a corrected oxygen concentration output based on non-corrected indication of oxygen concentration and the indication of process pressure. A method of providing a process oxygen concentration using a process oxygen analyzer coupled to an industrial combustion process is also disclosed.
