Pressure sensor for contact free pressure measurement using an elastic non-conductive material as the sensitive element

摘要

The pressure sensor comprises a resonant loop and a hollow body (1) comprising an elastic, preferably non-conductive material as a pressure sensitive element. Preferably, the hollow body (1) carries a strip-type conductive coating (2) which may be connected to a capacitor. The hollow body (1) may be made up of an undefined number of individual hollow bodies of undefined geometry.
