METHOD FOR PROTECTING RESONATING SENSORS AND PROTECTED RESONATING SENSORS
First Claim
1. A method for providing a protected resonating sensor, the method comprises the step of enclosing one or more resonating sensor units in at least one chamber having at least one compliant member, each sensor unit of said one or more resonating sensor units has at least one resonating part, said at least one chamber is filled with a substantially non-compressible medium, said at least one compliant member forms at least part of the walls of said at least one chamber, said at least one compliant member and said at least one resonating part are in contact with said substantially non-compressible medium.

Abstract
A protected resonating sensor may include at least one resonating sensor unit. Each sensor unit has one or more vibratable members. The protected sensor includes a compliant member that forms part of one or more chambers. A first side of the compliant member may be exposed to a medium in a measurement environment. The sensor unit may be any resonating sensor unit having a resonance frequency that depends on the value of a physical variable in a measurement environment. The protected sensor includes a substantially non-compressible medium disposed within the chamber(s). The substantially non-compressible medium may be a liquid or a gel. When the medium is a liquid, the chamber is sealed. When the medium is a gel, the chamber may be sealed or non-sealed. The medium is in contact the vibratable member(s) and with a second side of the compliant member. The medium may have a low vapor pressure. The protected sensor may also be attached to or included in or formed as part of any suitable device or sensor anchoring device and may also be implanted or inserted into a body or an organism. Methods are described for constructing the protected sensor.
