Abstract
A particle sensor uses an electrostatic particle charging section in the form of an ionization chamber. A flow sensor arrangement is used to produce a signal which is representative of the amount of gas flow between the outside of the ionization chamber and the inside of the ionization chamber. This information is indicative of the flow conditions, and can be used to determine when adverse flow conditions are present which may adversely affect the performance or lifetime of the particle sensor.
