Do you supply numbers for Kapton insulated thermocouples?
We can supply silicone rubber impregnated fiber glass numbered tubes for thermocouples that are to be used up to 250 ºC. Above this temperature, you can make numbers inexpensively by getting 0.010” to 0.020″ thick soft aluminum shim stock and cutting 0.5” by 1.5” strips and punching 1/8” holes in each end and scribing the numbers with a ball point pen. The thermocouples fit very nicely through the holes and do not require the thermocouple wire to be deformed to string the numbers. Some suppliers will sell you 1” diameter, 0.03” to 0.04” thick disks with stamped numbers with the same two holes that require that the thermocouple be seriously deformed to install. This deformation has the potential to cold work the wire affecting calibration and also damaging the Kapton insulation. The soft aluminum extends the life of your thermocouples and cost far less.
