Abstract:

The purpose of the Space Technical Data Report STDR is to familiarize personnel with the operation and service instructions for the Helium Leak Detector Cabinet, 52E420097-1 and 52E420097-101. The two configurations are functionally the same with the 52E420097-101 assembly incorporating a modified leak detector with ultra high sensing capabilities for hydrogen leak detection. The information contained in this document pertains to both detectors however, only the Helium Leak Detector will be mentioned. Addendum A contains information pertaining to the Hydrogen Leak Detector, which differs from that of the Helium Leak Detector. The STDR presents a description of the detector, its control and indicator functions, and service instructions for preventive maintenance. Author
