Abstract
Abstract For monitoring a plurality of pressurized cables and supplying electrical signals in accordance therewith, there is provided a cannister arrangement of transducers. The cannister is provided with a closure by which the cannister is pivotally mounted. The closure is provided with a plurality of bores through which pressure medium can be transmitted. The transducers are mounted on the closure and communicate through the bores with a plurality of armored hoses supplying pressurized medium originating in the pressurized cables which are being monitored. A plurality of wires ae bundled together into a cable which is mounted on the closure, the wires extending through the closure for connection to printed circuits which lead to contacts with which the transducers make electrical connection. The wires connect the transducers to a monitoring device or the like. The arrangement is particularly suitable for use in connection with monitoring pressurized telephone cables.
