Abstract
A sensor system for detecting particles within a fluid, the sensor system comprising: i) a gauge body having a working surface for receiving a particle containing fluid; ii) an impactor spaced apart from the working surface of the gauge body defining a spacing between the impactor and the working surface of the gauge body through which particle containing fluid can pass, wherein the sensor system is configured such that as the particle containing fluid passes through the spacing between the impactor and the working surface of the gauge body, particles disposed over the working surface are impacted by the impactor generating a signal which is dependent on one or both of the size and concentration of particles in the fluid; and iii) a sensor configured to detect the signal generated by the particles impacting the impactor and provide an output signal.
