  • Heating cable control and monitoring method and system
    Patent number: 5900179
    Abstract: A method and system for controlling heating cables wherein a plurality of two-conductor heating cables are disposed in contact with heatable vessels to heat the vessels. Power lines having at least two conductors are connected to the heating cables through a plurality of first switches. Each first switch is responsive to a control signal for selectively connecting and disconnecting one heating cable to and from the power lines. Each of a plurality of remote terminals is connected to the two conductors of a heating cable and detects the temperature of the heatable vessel heated by the heating cable. At least one main controller for controlling a plurality of first switches is connected to two of the power line conductors. Temperature data relating to temperatures detected by the temperature sensors is transmitted from the remote terminals over the heating cables and the power lines by spread spectrum data transmission to the main controller.
    Type: Grant
