ABSTRACT:
A dual functionality temperature control measurement and low water cutoff measurement system is taught within a single tapping to a boiler. This dual functionality combines a low water cutoff and temperature sensor into one control utilizing a sensing element suitable for use in a single existing tapping for a boiler. Independent of low water functionality, the temperature sensor is also capable of monitoring temperature as a replacement probe in an existing temperature sensor-only well. A conductive member provides a compression fit inside the probe well for thermistors, while simultaneously providing conduction with the well interior for a low water cutoff signal in a two-conductor well.
