摘要： A transparency, e.g. an aircraft laminated windshield, includes one or more moisture sensors to monitor moisture penetration to monitor performance of the moisture barrier. At least one of the moisture sensors includes a dielectric between and in electrical contact with two electrically conductive electrodes. Alternating electrical current is applied to the electrodes to measure the complex impedance (ohms) of the dielectric to determine the amount of moisture within the laminated windshield in the area of the moisture sensor. With the information provided by the moisture sensors performance of the windshield is available to schedule timely repair or replacement of the windshield that is performing outside of acceptable limits.

摘要： An apparatus for measuring a moisture content value within a volume. A frequency generator generates at least one source signal at frequencies of no more than about one kilohertz. Probes are disposed with surfaces in physical contact with the volume, where no direct current flows between the probes through the volume. One of the probes is electrically connected to the frequency generator as a source probe, and adapted to receive the source signal and emit the source signal into the volume, thereby creating an electrical field having characteristics that are dependent at least in part on a moisture content of the volume. Another of the probes operates as a receiver probe for sensing the electrical field and producing 10 an output signal having an output property that is dependent at least in part on the source signal and the moisture content within the volume. Means are provided for producing a moisture content value for the volume, where the moisture content value is based at least in part on the output property of the output signal.

摘要： An apparatus measures moisture content of cotton based upon rates of electrical charges flowing through the cotton. The apparatus includes a moisture sensor having first electrodes, second electrodes, and ground electrodes which are interdigitated between the first and second electrodes. The apparatus also includes a moisture content determination circuit that provides first electrical charges to the first electrodes, and second electrical charges to the second electrodes. The moisture content determination circuit determines the rate of electrical charge flowing from each of the first and second electrodes through the cotton to the ground electrodes, and determines the moisture content of the cotton based upon the rates of electrical charges flowing through the cotton. By thus applying first electrical charges to the first electrodes and second electrical charges to the second electrodes, the apparatus accurately measures the moisture content of the cotton over a wide range of moisture contents. This wide range is achieved by setting the first electrical charges of the first electrodes to a level which is optimal for moisture levels at the upper end of the desired measurement range, and by setting the second electrical charges on the second electrodes to a level which is optimal for moisture levels at the lower end of the desired measurement range.

摘要： The invention relates to a moisture meter for determining the moisture content of particulate material. The moisture meter comprises a frame part (1), a space (2), a measuring cup (3) disposed within said space (2) for receiving a sample of the particulate material which moisture is to be measured, and moisture measuring means. The moisture meter comprises a swiping means (9) for removing at least partly a part of a sample of particulate material which moisture is to be measured, which part of the sample of particulate material extends out of the inner space of the measuring cup (3) through the open end of the measuring cup (3). The swiping means (9) are movably attached to the frame part (1) for movement in a swiping path where a swiping member (10) of the swiping means (9) is configured to move essentially along the open end of the measuring cup (3).
