PROBE FOR USE IN DETERMINING AN ATTRIBUTE OF A COATING ON A SUBSTRATE

摘要

A probe (40) provides electrical communication between a coating (42) and a processing system. One optional feature includes an outwardly projecting, electrically conductive engaging member (66) that is held in a captivation structure (62, 64) releasably retained in a housing (50) and engages a contact (54) that is inside the probe (40) and connected with the processing system. Another optional feature of the probe (40) provides the electrically conductive engaging member (66) in the form of a pin (66) or pins (66) captivated in a light-transmissive structure (62, 64) adjacent a light-emitting source (58). Another optional feature of the probe (40) includes a restraining structure (62, 64) that defines a frustoconical seat (180) for engaging a conical distal end (170) of an electrically conductive pin (66) that is adapted to contact the coating (42).
