Ultra Fine Wire On several occasions Concept Alloys has been asked to supply matched tungsten-rhenium thermocouple alloys at sizes smaller that the .003” diameter we normally stock.  Recently we have quoted on sizes

Thermocouple Application Note 8 How to Weld Tungsten-Rhenium Thermocouple WireJoining of tungsten and tungsten-rhenium alloys has been done using a variety of techniques from gas welding to ultrasonic welding. However, for joining wires to produce

What is a “double reversal” in a thermocouple circuit? Thermocouple circuits often have several connection points along their length. These may be from the thermocouple to lead wire, lead wire to connector, or at other

What are "405/426" alloys, and how do they differ from other Type C compensating extension wires? “405/426” are alloy designations assigned many years ago by Hoskins Manufacturing Company. The original 405/426 alloys are nickel base

What is the significance of resistance in a thermocouple circuit? In its’ simplest form a thermocouple consists of two thermoelectrically dissimilar materials joined at two points. If there is a temperature differential present

Why can’t chemical analysis alone always solve failure problems? Chemical analysis of a failed thermocouple is often an important step in determining the cause of failure. Analysis of the wire, insulators and sheath can identify
