摘要： A system and method for counting opaque particles within a fluid sample. The system uses an optical lens system to focus a light beam onto a sample on a multi-dimensional translation stage. The translation stage is moved in a pattern such that the intensity of the transmitted light is measured as a function of path length. A photo detector is used to measure the transmitted light through the sample. An analog-to-digital converter quantifies the transmitted light intensity. Changes in light intensity along the path length are correlated with the detection of an opaque particle. Data processing algorithms are implemented to automatically determine the background noise level associated with the acquired data and to set a discriminator level above which a particle is registered. The total number of particles and an areal density is reported along with an estimate of the uncertainty.

摘要： A corrosion monitoring device for monitoring corrosion in fluid containing systems and other equipment exposed to a corrosive environment comprising sensor elements having a composition substantially the same as the equipment being monitored, the sensor elements having a predetermined thickness for exposure to a corrosive solution of the fluid containing system. An electrical property of the monitoring device changes when corrosion penetrates through the thickness of the sensor element. A digital output device generates a first binary signal when corrosion has not penetrated through the thickness of the sensor elements, and a second binary signal when corrosion has penetrated through the thickness of the sensor elements. Multiple sensor elements may be used to provide multiple binary signals. Information from the digital outputs may be processed to provide a cumulative log of corrosion measurements.
