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.
A removable probe insertable within a well in a boiler tapping comprising a removable low water cutoff sensor in electrical communication with said well interior by a resilient flexing connection, said low water cutoff sensor and said resilient flexing connection forming a slideably removable electrical connection.
A removable probe insertable within a well in a boiler tapping comprising a low water cutoff sensor in electrical communication with said well interior, said electrical communication formed by a resilient flexing connection, said low water cutoff sensor including a conductive member comprising a solidly-shaped conductive material, said solidly-shaped conductive material in electrical communication with said well interior without soldering or welding said conductive member to the interior of said well, such that said low water cutoff sensor and said resilient flexing connection form a slideably removable electrical connection.
A system for monitoring low water cutoff and temperature in a boiler comprising:
