Isolated Sensing Device Having an Isolation Housing
Abstract
An isolation housing is used to isolate a sensor, such as a hydrophone, from pressure fluctuations or other adverse conditions caused by fluid flow in a fluid environment. The isolation housing includes a cap portion that receives the sensor and fluid from the fluid environment. The isolation housing further includes a mounting portion that mounts the housing to a structure disposed in the fluid environment. When the sensor is a hydrophone, the cap portion is made from a material having an acoustic impedance that matches the surrounding fluid environment. The cap portion further includes one or more apertures allowing gas bubbles to escape from within the cap portion. The isolation housing further includes a retaining device, such as a resilient member, that retains the sensor centrally within the cap portion and isolates the sensor from structural vibrations or other adverse effects caused by the structure.
