  • Water conductivity monitoring circuit for use with a steam generator
    Publication number: 20070205160
    Abstract: A water conductivity monitoring circuit determines the status of an ion exchange filter in the water flow to a steam generator. A microprocessor sends a reference signal to a conductivity sensor circuit that converts it to an excite signal that is sent to a probe in the water flow. Any conductivity of the water alters the excite signal, and the modified signal is compared to the reference signal to establish a value indicative of the conductivity of the water. The microprocessor compares the value to at least two thresholds representative of the status of the filter.

  • Flammable vapor control system
    Patent number: 6722876
    Abstract: A safety device for shutting off the flow of gas to a gas-fired appliance in the presence of flammable vapors. The resistance of a variable resistance flammable vapor sensor is monitored by a microprocessor that controls the operation of a gas flow valve. When the measured resistance indicates the presence of a preselected concentration of flammable vapors, the gas flow valve is shut of and the ignition system cannot be energized.
