Abstract
An immersion well assembly for a fluid vessel, such as a boiler, hot water heater or piping system, having an existing threaded opening. A preexisting well housing a mechanical temperature sensor, which is connected to a temperature display or control first system, is removed from the opening, and the present assembly threaded therein. In this assembly are a (replacement) mechanical sensor to be connected to the first system and an electronic sensor. The electronic sensor is positioned in a small distal pocket and the sensor wires travel along a groove adjacent the mechanical sensor and out to a second system, such as a remote computer control system.
Claims45
A fluid vessel temperature sensing method, said method comprising the steps of:
- providing an immersion well assembly including an elongate member having a longitudinal cavity and first and second temperature sensors longitudinally arranged in the cavity and on a longitudinal axis of the cavity, wherein one of the first and second sensors is disposed in a distal pocket of the cavity;
- threading the elongate member into a preexisting threaded opening in a wall of a fluid vessel and thereby into a threaded-in position;
- and
- when in the threaded-in position, the first sensor transmitting a temperature thereby sensed of fluid in the vessel to a first device and the second sensor transmitting a temperature thereby sensed of fluid in the vessel to a second device.
An immersion well assembly, comprising:
- an elongate member having a portion configured to be secured into an opening in a wall of a fluid vessel such that said elongate member extends, when thereby in a secured-in position, into the fluid vessel and into fluid therein, said elongate member having a longitudinal cavity, and said cavity having a cavity central longitudinal axis;
- a fluid-containing first temperature sensor which senses the temperature of fluid in the fluid vessel by the change in pressure of the fluid of said first sensor, with said elongate member in the secured-in position, and transmits the temperature-indicating pressure change to a first device, said first sensor being on the longitudinal axis and in said cavity;
- an electronic second temperature sensor which senses the temperature of fluid in the fluid vessel generally at the same time as said first sensor senses the temperature, with said elongate member in the secured-in position, and transmits an electrical signal representative of the temperature sensed by said second sensor to a second device, said second sensor being on the longitudinal axis and in said cavity, and disposed distally relative to said first sensor;
- and
- a wire connecting said second sensor to the second device and along which the signal is transmitted, said wire passing within said elongate member and along said first sensor.
