THERMOCOUPLES
TLSC2
Description
This is a thermocouple sensor for industrial applications available in Type J, K, N, T and other grades upon request.
Various insert diameters and sheath materials are available. The thermocouple can be manufactured with either flexible tails, a quick disconnect plug or a combination of the two. The hot junction can be either “grounded” or “ungrounded” from the sheath. The thermocouple can be installed into a thermowell or directly into the process by means of an adjustable compression fitting.
These assemblies are very useful in measuring temperatures in the ferrochrome industry where lengths in excess of 15 meters are required and where molten metal splashing occurs.
