Abstract
A liquid level detector utilizing a housing having a wall portion defining a inner chamber. The inner chamber communicates to the exterior of the housing through an opening which also permits liquid to enter the chamber. A floatation element is pivotally located within the housing and includes a bridging conductor which rotates upwardly. The bridging conductor is capable of contacting a pair of terminals which constitute a portion of an alarm circuit.
Claims5
A liquid level detector comprising:
- a. a housing, said housing having a wall portion defining an inner chamber to permit entry of liquid into said chamber;
- b. a floatation element located within said housing inner chamber;
- c. alarm means, including an electrical circuit and electrical power means for activating said alarm means;
- said electrical circuit including a pair of conductor terminals spaced from each other and exposed within said inner chamber, said pair of conductor terminals being fixed to said housing wall portion in a particular orientation;
- d. a bridging conductor connected to said floatation element electrically connecting and physically contacting said pair of conductor terminals to complete said electrical circuit by conduction between said bridging conductor and said pair of conductor terminals;
- and
- e. pivot means for rotating said floatation element and said bridging conductor into stopped physical contact with said pair of conductor terminals, said floatation element being rotated by the buoyant force of the liquid in said chamber.
