Pressurized cable-sheath leak locating instrument |
摘要 |
A portable instrument used by maintenance technicians to assist in locating an air leak in a pressurized cable sheath. The instrument functions by limiting the area of search thus, permitting a timely repair of the leak to be made. The instrument is comprised of a set of pneumatic hoses that connect the instrument to the cable sheath; a pressure and flow transducer that respectively convert the pressure and flow to proportional d-c voltages; and an analog-to-digital converter that converts the analog voltages to equivalent d-c signals. The digital signals are applied to an electronics calculator that in combination with a keyboard and a computer program solves a set of mathematical equations that when solved, limit the area of search and ultimately provide the location of the air leak. The leak location data is viewed on a digital display and/or the data can be permanently recorded on a hard copy printer.
