  • Transducer systems
    Patent number: 9711709
    Abstract: Transducer systems with reduced acoustic noise coupling are disclosed herein. In some embodiments, a transducer system includes pressure balancing features to prevent a floating portion of the transducer system from contacting a fixed portion of the transducer system, or to reduce the degree to which the floating portion is urged into contact with the fixed portion by process pressure or atmospheric pressure. In some embodiments, a transducer system includes one or more acoustic dampening elements, interruption grooves, annular projections, or dampening washers to reduce acoustic noise coupling between various components of the transducer system or between the transducer system and a flowcell in which the transducer system is mounted.
