摘要： A capacitance transducer is provided herein for use in measuring loads. It includes a flexible first electrode, a flexible thin film solid dielectric and a fluid dielectric therebetween. A load which is applied to the transducer presses the first electrode, and the thin film dielectric against the second electrode, thereby squeezing out the fluid dielectric to increase the area of the electrodes that are in close proximity. This provides a capacitance transducer that has a significant linear response and an insignificant non-linear response.

摘要： A device and method are described for measuring the weight of objects using a pneumatically sealed bellows which contains a pair of spaced apart capacitor plates. In accordance with the invention, the pneumatic pressure within the bellows is varied to maintain constant dimensions for the bellows and a constant distance between the electric capacitor plates. This pressure is therefore a function of the weight placed upon the bellows which exerts a pressure tending to force the walls of the bellows and the capacitor plates closer together thereby changing the electric capacitance between the capacitor plates. By adjusting the pneumatic pressure to maintain a constant electric capacitance and constant dimensions for the bellows, a convenient parameter is obtained from which the weight of objects placed on the bellows can be measured. The invention has particular application in the meteorological sciences.

摘要： A capacitance mat for use in measuring loads includes a number of substantially horizontal electrode plates (of high strength aluminum) forming a capacitor with a substantially rigid dielectric material (e.g. nylon or fiberglass) separator disposed between the stacked substantially parallel electrode plates. The separators define spaces at which at least one of the electrode plates may bend in response to an applied load, to move with respect to each other, causing the capacitance of the mat to change. The separators may comprise a number of substantially parallel elongated strips of substantially rigid dielectric material spaced from each other in a dimension transverse to the dimension of elongation to define the spaces. At least first, second and third electrode plates may be provided, with the separator strips between the first and second plates substantially parallel to the strips between the second and third plates and located substantially centrally in the spaces between the strips between the second and third plates. The strips may be about 1/32nd of an inch thick and adhesively secured to the plates. Circuitry mounted on the mat detects the changes in capacitance resulting from bending of at least one of the electrode plates.

摘要： An improved capacitor-sensor formed between two rigid, closely-spaced and facing, first and second plates, each with a facing and nonfacing surface and with specific facing electrode patterns on the plates forming a plurality of capacitors sensitive to displacement between the plates, which will eliminate asymmetrical overlap patterns and horizontal motion sensitivity. The first and second plate electrode patterns each have three, equispaced, identical, circular conductive regions on their facing surfaces. The diameters of the first plate circular conductive regions are less than the diameters of the circular conductive regions of the second plate. Electrical leads and interconnections are so arranged that overlap between leads and interconnections on opposing plates is avoided.
