METAL CONTACT MEMBER FOR A MEASURING LANCE FOR TAKING MEASUREMENTS IN METAL MELTS

摘要

A metal contact member for a measuring lance for taking measurements in metal melts, said contact member consisting of two tubes interconnected by a tapered portion of one tube being pushed into the widened opening of the other tube with the interposition of an insulating member in the form of a sleeve, a cup-shaped insulating member being inserted into the widened interior of the end of the contact member and containing the contact by which the contact member is electrically connected to the measuring probe. The sleeve-shaped insulating member is sealed off from the wall of the widened portion of the tube and the wall of the tapered portion of the tube of the contact member by the insertion of annular seals while sealing of the cup-shaped insulating member from the wall of the widened interior of the tube end connected to the probe is provided by another annular seal.
