    摘要: An apparatus is provided, which includes a dust detector, a voltage source, and a controller. The dust detector includes two opposing surfaces and a conductive dust sensor. The two opposing surfaces are disposed in spaced, opposing relation to allow for the passage of airflow between the surfaces, and the conductive dust sensor is disposed at a surface of the two opposing surfaces. The voltage source is configured and controlled to establish an electrostatic field at least partially between the two opposing surfaces to facilitate directing conductive particles in the airflow passing between the two opposing surfaces towards the dust sensor. The controller monitors for a leakage current within the conductive dust sensor and determines whether the leakage current exceeds a predetermined trigger level indicative of the presence of conductive dust, and if so, automatically indicates a conductive dust warning.

    摘要: A corrosion sensor includes a plurality of metal strips having different thicknesses. A first metal strip with the least thickness is first employed to provide sensitive corrosion detection. After an exposed portion of the first metal strip is consumed, a second metal strip having a second least thickness can be employed to provide continued sensitive corrosion detection employing a remaining un-corroded portion of the second metal strip. The plurality of metal strips can be sequentially employed as exposed portions of thinner metal strips become unusable through complete corrosion and un-corroded exposed portions of thicker metal strips become thin enough to provide sensitive corrosion detection.
