摘要： A fluid detector for determining a presence of a fluid within a container, the detector including a sensor assembly with a lens and a sensor element that outputs a first ultrasonic signal in response to an input electrical signal. A generally cylindrical wall extends outwardly from an outer surface of the container and defines a housing with a cylindrical central bore having a base surface. The sensor assembly is coupled to the lens so that the lens focuses the first ultrasonic signal toward the wall. The sensor assembly is positioned such that it receives a second ultrasonic signal from the wall that results from the first ultrasonic signal. The sensor assembly then generates an output electrical signal corresponding to the second ultrasonic signal.

摘要： A fluid detector for determining a presence of a fluid within a container having a wall with an outer surface includes a piezoelectric element that outputs a first ultrasonic signal in response to an input electrical signal and a lens with an upper portion and a lower portion. A generally cylindrical wall is integral with and extends outwardly from the outer surface of the wall of the container and defines a cylindrical central bore having a base surface. The piezoelectric element is coupled to the upper portion of the lens so that, when the lens is disposed within the cylindrical central bore adjacent the base surface, the lens focuses the first ultrasonic signal toward the wall so that the first ultrasonic signal enters the wall. The fluid detector also includes an ultrasonic detector that, when disposed in a predetermined position adjacent the outer surface of the wall, receives a second ultrasonic signal from the wall that results from the first ultrasonic signal and that is affected in a predetermined manner by presence or absence of fluid at an inner surface of the wall. The ultrasonic detector generates an output electrical signal corresponding to the second ultrasonic signal.
