The Series TE-TNS Stainless Steel Thermowells are used to separate the instrument
from the surrounding media. When used with the Series TE and TE-I Immersion
Temperature Sensors, further protection is offered from aggressive media, high
pressures,andowrateswhileallowingforquickandeasyinstallationoftemperature
sensors without having to drain process media.
Thermowells are offered in both 304 and 316 stainless steel allowing for superior
corrosion resistance. Fabricated, or welded, thermowells are constructed from a
tubethatis closed at the tipbya welded solid tip. Solid-machinedthermowellsare
manufacturedfrombarstock.
