Abstract
A disposable thermocouple body is made from a lamination of flat paper plates. Sets of paper plates are of progressively increasing width up to the middle plate which supports a U-shaped thermocouple shield. The body is adapted to be mounted in one end of a lance for immersion into a molten metal bath.
Claims11
A disposable measuring head for sensing the temperature of a molten metal bath comprising a U-shaped thermocouple shield, a thermocouple supported within said shield, an insulating body supporting said shield, the body being characterized by a plurality of discrete flat plates having major faces laminated together, a plurality of the centrally disposed plates being longer than other plates, at least one of the centrally disposed plates having means supporting said shield at one end of the body an electrical contact means partially exposed on at least two of said plates, said contact means being electrically coupled to said thermocouple.
A disposable measuring head for sensing the temperature of a molten metal bath comprising a U-shaped thermocouple shield, a thermocouple supported within said shield, a generally cylindrical body supporting said shield, the body being characterized by a plurality of discrete flat insulating plates made from paper and having major faces bonded together, a plurality of centrally disposed plates being longer than other plates, at least one of the centrally disposed plates having means supporting said shield at one end of the body, said plates being generally rectangular and of progressively varying widths, at least two of the plates have an extension at the other end of the body with each extension having an electrically conductive layer thereon for forming an electrical coupling, each conductive layer being electrically coupled to one discrete end of the thermocouple.
