Capstone Design 2000 

Boeing has requested a design for an early warning leak detector for a hydraulic pump. The leak detector must be able to detect a mist; or a catch basin filled with hydraulic oil, or glycol based coolant. The leak detector will be able to warn a person in a control room located 100 feet away by a visual and audio warning.

Final assembly of product in process.

PrototypeThe system is fully operational. A smoke alarm, and a pair of infrared sensors, made it to the final product. The concept of using a motion detector, and a smoke alarm (infrared sensors) was used to give us an idea of how these sensors worked, as well as to have these sensors for the main project.

The prototype worked perfectly in our tests with a response time no greater than 13 seconds (approx). Details on testing are in the box to the right of this article.

Right now we are in the process of assembling all the parts into a rack-mountable enclosure that will go in the control room. The device is 3 rack spaces high (about 5 1/2 inches high), and has a visual/audio alarm as requested   

Our Capstone Design Presentation will be on April 28th, 2000 at 1:30PM in the Meadows Room of the Du Bois Conference Center. There will be a Poster Session in the Engineering Building following our presentation. Directions on how to get there here
