Manufactured from drilled bar stock, Watlow thermowells provide a pressure-tight connection at the point of installation. With thick walls, thermowells are sturdy enough to handle high pressure, high velocity and corrosive environments. They are frequently used in petrochemical and power plant applications. Highly critical or demanding applications may require thermowells not only for protection of the temperature sensor, but also to withstand high pressure, erosion or both, caused by material flows through vessels.
