1. Apparatus for detecting and locating leaks in a closed system having a plurality of coupled, sealed modules containing a confined fluid, said apparatus comprising:

  • a plurality of remote detectors each coupled to a respective module and including a mass spectrometer for detecting escape of the confining fluid from the closed system;

    a plurality of remote processing means for receiving, storing and transmitting data where each of said processing means is coupled to a respective one of said remote detectors;

    a means for serially linking said plurality processing means one to another with a first processing means being coupled to a central processing unit and where said linking is accomplished by a plurality of twisted pairs of conductors each coupling adjacent pairs of remote processors,and where said central processing unit provides a means for receiving an output signal and providing an operator of the system with an indication of escape of the confined fluid from the closed system and for providing operator initiated control inputs to said remote processors.
