4Measurement DevicesThermowellsThermowells are recommended toprotect Swagelok dampened-movementbimetal thermometers from damagethat could result from contact withpressurized, corrosive, flowing, viscous,or abrasive process fluids. They alsoenable removal of thermometers forreplacement or service without affectingthe process or system.DimensionsDimensions, in inches (millimeters), are for reference only and are subject to change.The U dimension is the depth the thermowell is inserted into the fluid system and isspecified in the ordering number.
