  • Alarm system for monitoring the temperature of a liquid contained in a reservoir
    Patent number: 4612537
    Abstract: An alarm system and method for monitoring the temperature of a liquid contained in a reservoir. The system comprises a temperature sensing probe for sensing the temperature of the liquid. A sensing circuit is associated with the probe to generate a temperature indicating signal representative of the liquid temperature. A calibration circuit is provided for calibrating the temperature signal relative to a reference signal. Converter means is provided to convert the calibrated temperature signal to a binary signal indicative of sensed temperatures of the liquid whereby to feed comparator circuits having preset limit detectors to initiate an alarm signal when the temperature signal exceeds a predetermined value. The comparator circuits also feed a display device to indicate the temperature of the liquid.
