Abstract:
1. A removable probe having a dual measurement function within a well inserted in a boiler tapping comprising: a temperature sensor including at least one thermistor in a housing; thermistor conductors connecting to said at least one thermistor and protruding from said housing; a low water cutoff sensor including a conductive member connecting to a low water cutoff conductive wire, and forming a compression fit against said well interior securing said temperature sensor and a portion of said low water cutoff sensor to the interior of said well, said conductive member and said low water cutoff conductive wire in electrical communication with said well, such that said conductive member and said low water cutoff conductive wire are at approximately the same voltage potential as said well, wherein said conductive member comprises a resilient, compression-fit conductor in the form of a shaped wire clip, a peripheral or semi-peripheral resilient conductive band, or a solidly-shaped conductive material, compress fitted within said well interior to form electrical contact with said well interior without soldering or welding said conductive member to the interior of said well.
