W30, W40

Bar-stock thermowells, stepped shank, with threaded connection, NP100

Thermowells are used to to protect the measuring instrument from corrosion, high pressure or hgih fluid velocity and to allow the measuring instrument removal for recalibration or replacement without affecting the process system. The W30-W40 serie includes bar-stocked thermowells with a threaded process connection and they are suitable for heavy work conditions. These thermowells have a stepped-shank immersion length for a better process temperature measuring sesibility.
