TRANSDUCER SYSTEMS
First Claim
1. A transducer system, comprising:
- a transducer head having an ultrasonic transducer disposed therein;
a transducer stem extending from the transducer head; and
a decoupling feature configured to reduce acoustic coupling between the transducer system and a housing when the transducer system is mounted in the housing.

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.

3. A transducer system, comprising:
-
a transducer head having an ultrasonic transducer disposed therein and having a first surface configured to be exposed to process pressure when the transducer system is mounted in a flowcell; a transducer stem coupled to the transducer head and extending therefrom; and a pressure mounting assembly in which at least a portion of the transducer stem is disposed, the pressure mounting assembly having a first pressure balance surface configured to be exposed to process pressure when the transducer system is mounted in a flowcell; wherein the first surface and the first pressure balance surface face in opposite directions such that process pressure acting on the first pressure balance surface offsets process pressure acting on the first surface. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
