When doing tests on batch annealing furnaces and refractory dryouts we often have to run several lines of thermocouple wire into the furnace and attach then to the load pile and/or refractory wall/roof. these are sacrificial as once at higher temps the lines will burn out, and the process is not critical that an error of a couple of degrees is going to cause issue.
in the past, junctions have been made from twisted and crimped ends, and then the wire run right out and direct to the device.
what i am trying to gauge is the accuracy, or lack there of. would it be better to use higher rated thermocouple wire for the tip? would be significantly better (to justify the cost) to do the whole thing with thermocouple wire?
about 1500 f is the limit of what we would be interested in. i know most wire is only rated for 900, but not interested in what they 'calibrate for' or guarantee.
any and all knowledge and experience welcome as always!
