Sampson Control and Bi-Metallic Air Intake Damper Question

Silly question for the day. The Sampson Control seems to be synonymous with hand fired boilers, and the Bimetallic Air Intake Damper (Regulator) seems to be common on hand fired stoves. What is the essential difference between these two devices (besides boiler vs. stove)? Do they basically function the same way?

sampson control has a probe in the water of boiler, regulator has a sensing element near stove. Other than that they function the same.

Thanks Eric! I wonder if the Sampson uses thermal expansion wax instead of a bimetallic coil spring?

Bi-metallic spring, I have had one apart.
