ABSTRACT:
A means and method for detecting the presence of electrically conducting fluid whereby a signal is actuated upon the presence of fluid. The method of the invention includes placing two conducting members at the location to be monitored. A gating device having an electrical pathway to the signal device is actuated upon receiving sufficient biasing voltage. A voltage dividing network allows sufficient bias in voltage in two ways, either by the shorting of the two conducting members of the probe by electrically conducting fluid, or by the breaking of the circuit path between the electrical power source and the probe ends. The means of the invention utilizes a gating device having a biasing input connected to the middle of a voltage dividing network. Two conducting elements of a probe are attached to a point before the voltage dividing network and in the middle of the voltage dividing network respectively. A non-falsing circuit, a battery level circuit, and a remote alarm interface circuit can be added to the fluid detecting circuitry.
