Honeywell 121371M Immersion Well Assembly 3/4" NPT Male 3" Insulation

The Honeywell 121371M Immersion Well Assembly is an assembly well suited for use in temperature sensing in HVAC systems. It has a 3/4” NPT male connection, 3” of insertion length and is designed to shield temperature sensors from aggressive process parameters such as high pressure and corrosive fluids. The creation of a sealed pocket makes it possible to remove a sensor without having to turn off the system. This assembly is typically applied in boilers, chillers, and hot water systems and has advantages of higher accuracy in temperature control, lower thermal inertia, and higher durability of the sensor, providing dependable control of the HVAC systems.
