Abstract
An insert apparatus for installing a transducer assembly in a sensor port of a flow cell is disclosed. The transducer assembly is installed in the cavity of the insert body without the use of glues or adhesives to bond the transducer assembly to the cavity.
Claims20
An apparatus for installing a transducer assembly in a sensor port of a flow cell comprising:
- an insert body configured for insertion into the sensor port, the insert body defines a cavity having a opening located at a first end of the insert body and an ultrasonic buffer at a second end of the insert body;
- a transducer assembly located in the cavity of the insert body, the transducer assembly comprises a housing having a first end, a second end proximate to the ultrasonic buffer opposite of the first end of the housing, and a piezoelectric crystal located in the second end of the housing;
- a holding nut located in the cavity proximate to the first end of the housing applying a compressive force to the housing to keep the second end of the housing proximate to the ultrasonic buffer;
- a coupling material in fluid form located in an area between the second end of the housing and the ultrasonic buffer;
- and
- a first o-ring located in the cavity proximate to the housing to assist in preventing the leakage of the coupling material from the area between the housing and the ultrasonic buffer.

An apparatus for installing a transducer assembly in a sensor port of a flow cell comprising:
- an insert body configured for insertion into the sensor port, the insert body defines a cavity having a opening located at a first end of the insert body and an ultrasonic buffer at a second end of the insert body;
- a transducer assembly located in the cavity of the insert body, the transducer assembly comprises a housing having a first end, a second end having an exterior surface in contact with an interior surface of the ultrasonic buffer opposite of the first end of the housing, and a piezoelectric crystal located proximate to the interior surface of the second end of the housing;
- and
- a holding nut located in the cavity proximate to the first end of the housing applying a compressive force to the housing to keep the second end of the housing in contact with the ultrasonic buffer,
- wherein the exterior surface of the second end of the housing and the interior surface of the ultrasonic buffer are polished to eliminate voids between the exterior surface of the second end of the housing and the interior surface of the ultrasonic buffer when the exterior surface of the second end of the housing is in contact with the interior surface of the buffer.
