ABSTRACT:
A flexible, rope-type heat sensor interfaces in a overlapping array with exposed outer portions of U-shaped heating elements of an immersion-type heater. The sensor is connected to a controller which opens and closes circuitry connecting the heater with a power source upon selectively sensing a temperature condition of the heater elements. With such a heater installed in a liquid-containing receptacle, the temperature of the liquid can be controlled and the heater protected from inadvertent overheating. The device is also applicable to control liquid level in a receptacle.
