Abstract

The application of the Electro-Optic Sensor and Force transducer on leak detection began with reviewing various leak testing technologies and their associated problems. Specific applications of differential pressure sensors for leak testing are discussed and the specifications of the University of Arkansas Electro-Optic Sensor and Force Transducer are explained. A design for a new differential pressure transducer based on the University of Arkansas Electro-Optic is presented. A leak tester was assembled by using a prototype of a differential pressure transducer. The performance test and calibration of the unit was accomplished by using a standard calibrated leak. The calibration results were then used to estimate the leak rate of some unknown samples. In order to reduce the ambient effect, a balance volume was attached to the reference chamber. In conclusion, a discussion of the problems and limitations is presented.
