Rosemount 114C Flanged Thermowell
Rp123000.00
The Rosemount 114C Flanged Thermowell is a heavy-duty, barstock thermowell designed to protect temperature sensors (such as RTDs or thermocouples) in demanding industrial processes. The 114C series ensures robust mechanical integrity and process compatibility, offering flexibility in mounting styles, materials, and customization to suit varied process conditions.
The flanged version conforms to industry standards for flange connections, ensuring reliable and secure installation in process piping or vessel nozzles. Built from solid barstock, it provides strength and integrity under pressure, temperature, and flow stress. Optional testing, such as hydrostatic pressure, dye-penetration, and material certification, ensures compliance with stringent industrial requirements.
The 114C Flanged Thermowell is widely used across sectors such as petrochemical, oil & gas, chemical processing, utilities, and general industrial temperature measurement applications.
