2010-12-19 · Your current pressurestat operates on measuring the pressure in the steam boiler and switches manual contacts on or off to control this. If the noise of the contacts is too loud, you will need to replace the pressurestat with a PID, thermocuple, and solid state relay, and this will have to be on the steam boiler, because that's where the current clicking pressurestat is.

Fusible plug - Wikipedia

2019-6-15 · A fusible plug is a threaded metal cylinder usually of bronze, brass or gunmetal, with a tapered hole drilled completely through its length. This hole is sealed with a metal of low melting point that flows away if a pre-determined, high temperature is reached. The initial use of the fusible plug was as a safety precaution against low water
