ABSTRACT:
A fluid detection system capable of detecting the smallest amount of liquid chemicals, mixtures, aqueous solutions, pure water and others by detecting very low levels of resistance or conductance due to ionization when the liquid substances are subjected to very small amounts of electrical power in a small and localized sampling area. The system includes an electronic control module and a sensing probe. The control module provides strictly limited and controlled amounts of electrical voltage and current to one or more remotely located sensing probes which detect the level of resistance or conductance between two electrodes (gold pins) disposed at a fixed distance from one another. The voltage developed across the electrodes is input to a comparator circuit in the electronic module and compared to a reference to produce a signal defining either a dry or a wet (leak) condition of the sensing probe. This signal can be utilized to generate shutdown signals and/or audible and visual alarms. The detection system can also be used to very accurately detect fluid levels.
