24C512 Bimetal Thermowell 304SS

The Value Brand 24C512 is a bimetal thermowell constructed from 304 stainless steel for industrial temperature measurement. It suits process engineers and maintenance technicians who need a straight-shank threaded well for sensor insertion in piping systems. The 1/2 NPSM connection provides a standard mechanical fit. Buyers who need a food-safe rated well or a different insertion length should select another model.

Thermals noise and power draw

This passive mechanical component generates no heat, noise, or electrical power draw during operation. The 304 stainless steel body withstands process temperatures and pressures without active cooling. Thermal response depends on the installed sensor and process media velocity. No power supply or acoustic considerations apply to this hardware.

Questions about this item

How do I install the 1/2 NPSM bimetal thermowell and what step is often missed?

Thread the 3/4 in MNPT connection into the process fitting, then insert the probe so its stem matches the 2 1/2 in insertion length; the step often missed is confirming the 1 3/4 in neck extension clears insulation or piping before final tightening.

What maintenance or replacement will the 304 stainless steel thermowell need over time?

Inspect the 304 stainless steel shank periodically for corrosion, erosion or thread damage; replace the thermowell if the straight shank shows pitting, the 3/4 in MNPT threads deform, or the probe no longer seats at the full 2 1/2 in insertion depth.
