摘要： A semi-permanent reference electrode for use in monitoring and measuring metals in field applications, such as cathodic protection. This electrode has an outer electrode body with a cap and porous plug. The outer electrode body is filled with a fill solution which is a saturated salt solution formed from a solid salt. The solid salt is hygroscopic with a low deliquescence point. An opening is provided in the cap to allow moisture into the outer electrode body to combine with the fill solution to maintain the saturated salt solution in the field. This saturated salt solution must maintain a constant pH for use in the semi-permanent reference electrode. A wire is used within the outer electrode body which connects to a voltmeter. This voltmeter measures the potential difference between the reference electrode and the field component of interest, which can include pipelines, storage tanks and bridges.

摘要： A system and method for monitoring the effectiveness of a coating on a substrate surface and indicating the failure of the coating to adequately protect the surface from corrosion, degradation, and the like. The system includes a sensor array positioned in contact with the coating utilizing a number of sensor electrodes connected to a single integrated circuit or a number of separate individual sensor circuits. The electrodes of the sensor array make measurements of the electrochemical impedance characteristics of the coating and provide such data by way of telemetry to a data interrogation device that is periodically be placed in proximity to the sensor array. The interrogation device may serve to both power the sensor array and trigger it to acquire data. A nominal parameter N′, which is the product of the impedance magnitude and the phase angle, is utilized as a direct indication of the resistance and capacitance characteristics of the coating and therefore a direct indication of the coatings effectiveness.
