Thermometers and transmitters for the process industry. BASI offers a complete assortment of thermometers, thermowells,
measurement inserts, transmitters and accessories for all types of process industries such as Oil & Gas, Chemicals, Food & Beverage, Life Sciences, Primaries & Metal, Power & Energy.


The thermowell is the process wetted part of the thermometer. Basically, thermowells are divided into protection tubes constructed from welded tubes and thermowells made of drilled barstock material.  In many cases temperature sensors cannot be placed directly into the medium but need protection from rough process conditions. Furthermore the thermowell makes sure that an exchange of the measurement insert is possible without interrupting the process.
