Beschreibung
Zusammenfassung:	A plug installation apparatus comprises a mechanism for moving an internally captured expander member (26) relative to a plug (24) wherein it is captured thereby expanding the plug (24) into contact with the internal surface of a tube (18) within which the plug (24) is disposed. The apparatus further comprises a sensor mechanism (50) for determining that the plug (24) has been properly inserted in the tube (18) prior to expanding the plug (24) for preventing improper expansion of the plug (24). The apparatus may also have force measuring devices (38) for determining and verifying that the proper amount of force has been applied to the expander member (26).
