Measuring device comprising a resonator having a film carrier

摘要

The invention relates to a measuring device (10, 50) comprising a resonator (20, 52) having a sensitive) being inserted in the region and a base support unit (26, 30) for measuring properties of a fluid, the resonator (20, 52base support unit (26, 30) and contacted therein, the sensitive region remaining accessible to the fluid, and the resonator (20, 52) being activatable via connection points (24, 40) on the base support unit (26, 30). The invention is characterized in that the base support unit (26, 30) is formed solely by a film arrangement.

主权项

1. A measuring device (10, 50), comprising:
a base support unit (26, 30); said base support unit comprises a film arrangement; said film arrangement includes a bottom film, a support film, a spacer film and a final film; a resonator (20, 52), said resonator includes a periphery; said bottom film affixed to said support film, and said spacer film affixed to said support film; said support film includes electrical contacts, electrical conductor paths (27, 42) and electrical connection points (24, 40); an electrical source for engagement with said electrical connection points; said electrical conductor paths (22, 42) in electrical communication with said electrical contacts and said electrical connection points (24, 40) of said support film; said resonator includes a sensitive region for measuring properties of a fluid, and, said sensitive region of said resonator accessible to said fluid; said resonator includes electrical contacts; said electrical contacts of said resonator engage said electrical contacts of said support film, and thus, said electrical contacts of said resonator are in electrical communication with said electrical connection points via said electrical conductor paths (22, 42); said spacer film includes a first opening therein and said resonator resides within said first opening of said spacer film; said final film includes a second opening therein, and, said final film engages said spacer film and said periphery of said resonator; said final film includes a third opening and a fourth opening, said third opening aligned with one of said electrical connection points and said fourth opening aligning with the other electrical connection points, said third and fourth openings of said final film enabling engagement of said electrical source with said connection points for activation of said resonator (20, 52).
