A fluid detector 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 housing is integral with an outer surface of the wall of a container and defines a cylindrical central bore for receiving the lens. The piezoelectric element is coupled to the upper portion of the lens so that the lens focuses the first ultrasonic signal toward the wall so that it enters the wall. An ultrasonic detector is disposed adjacent the outer surface of the wall, for receiving a second ultrasonic signal from the wall that results from the first ultrasonic signal and that is affected by the presence or absence of fluid. The ultrasonic detector generates an output electrical signal corresponding to the second ultrasonic signal.
G01F 23/28 - Indication ou mesure du niveau des liquides ou des matériaux solides fluents, p. ex. indication en fonction du volume ou indication au moyen d'un signal d'alarme en mesurant des variables physiques autres que les dimensions linéaires, la pression ou le poids, selon le niveau à mesurer, p. ex. par la différence de transfert de chaleur de vapeur ou d'eau en mesurant les variations des paramètres des ondes électromagnétiques ou acoustiques, appliquées directement au liquide ou au matériau solide fluent
An apparatus (10) for sensing a condition, such as humidity, through an opening (20) in a surface (12) such as a duct or wall. A housing (14) includes an outer section (16) mounted on the surface and a probe section (18) extending into the duct or wall. A circuit board assembly (32) is mounted within the housing and includes a user interface section (34) within the housing outer section and a sensor section (36) rigidly connected to the user interface section and extending into the housing probe section. The sensor section may be integrated into the circuit board assembly by a rigid connector (42) allowing easy removal and field replacement of the sensor section. A sealing device (56) isolates the housing outer section from the air within the duct or wall. A flexible grounding connection (66) provides electrical grounding of the circuit board assembly and a degree of mechanical support.
