Beaded Wire Thermocouple
BJWE offers 24 hour delivery (or
better) on most beaded wire thermocouples. These thermocouples consist of a piece of
insulated thermocouple grade wire, cut to length, with a thermocouple weld on one end (hot
or sensing end), and stripped leads on the cold end. Wolfe Enterprises uses a special
Tungsten Inert Gas Welder in an argon atmosphere for the weld. Beaded wire thermocouples
are excellent low cost solutions to measure air and surface temperatures. Water resistant
teflon caps, connectors, and stainless steel overbraiding are available.
