Gas and Particle Sensor Using Voltage and Current Behavior Between Electrodes During Glow-to-Arc Transition : 11,959,878

A sensor for detecting properties of a gas, gas mixture, or a gas or gas mixture containing particles, all collectively referred to as a “gas”. A flow tube contains a pair of electrodes arranged such that at least a portion of the gas flows between the electrodes. A controller applies voltage to the electrodes and measures response data from the electrodes representing the voltage-current relationship between the electrodes while the gas is between the electrodes. Based on the response data, the controller determines a concentration of particles within the gas.
