BAPI Thermowell

BAPI Thermowells are hollow tubes used to protect Immersion Probe Temperature Sensors to be not directly in contact with pipe contents.  They are installed permanently to pipes and the BAPI-Box Immersion Probe Temperature Sensors are inserted to measure the pipe contents' temperature.

Available in 304 stainless steel (machined), 316 stainless steel (machined), brass (machined), and two-part (welded) 304 stainless steel.  These materials do provide satisfactory corrosion resistance but when selecting you must consider the material and strength depending on the application.

We offer 2", 4", and 8" well length with 1/2” NPT external and 1/2” NPSM internal.  You also have the option to request customized lengths.

Note: Do not use two-part welded stainless steel thermowells in moving water but applicable in catch basins, sumps, or large storage tanks that have a small inlet and outlet pipes.  It must not be closely mounted to the inlet or outlet pipe of the tank.
