ABSTRACT A debris detector for a particle counter. A particle, or transient debris passing through the sensing orifice causes a voltage pulse. When debris lodges in or against the orifice , a d.c. voltage shift occurs. The voltage at the orifice is capacitively coupled to an amplifier and the output of the amplifier is provided to an integrator. The integrated voltage is applied to a comparator to provide an output signal whenever the integrated voltage exceeds a reference voltage. The comparator output signal is provided to a delay circuit having a delay related to the time required for a particle to pass through the orifice. If the comparator signal remains after the delay time, a debris alarm signal is provided.
