B. J. Wolfe Enterprises, Inc

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.
