Spring force nodal mounting method for resonator sensor

摘要

A resonator in the fluid for displacing the fluid has a sensing section and a non-sensing section. A compression contact member coupled to the mounting body compressively secures the resonator non-sensing section in a mounting body. The apparatus may further include a pressure feed through module received in the mounting body that is in signal communication with the resonator.

1. An apparatus for determining a property of a fluid, comprising:
a resonator in the fluid, the resonator having a sensing section and a non-sensing section; a mounting body in which at least a portion of the resonator non-sensing section is disposed; a pressure feed through module received in the mounting body; an electrical connection member configured to transmit signals between the pressure feed through module and the resonator; and a compression contact member coupled to the mounting body, the compression contact member compressively securing the resonator non-sensing section in the mounting body, the compression contact member being substantially separate from the electrical connection member, wherein the compression contact member has a reduced contact area that contacts the resonator non-sensing section at a nodal line of the resonator non-sensing section.
