Nucleonic gauge for determining lubricant level in a joint and method |
摘要 |
A nucleonic gauge (10) is disclosed for effectively assessing the amount of lubricating fluid in a hinge joint (12) having an elongate reservoir (23) without disassembly of the joint. The gauge includes a disc-type radiation source (54) at one end of the joint for emitting radiation cooperatively with respect to the lubricant reservoir and providing a substantially collimated beam pattern (60), and a detector element (64) in the path of the pattern at the other end of the joint for measuring the radiation activity.
