摘要： The liquid level detector system of the present invention comprises a heater thermally coupled to the interior of the vessel. A linear sensor, having a vertical longitudinal axis, is located in proximity to the heater such that discrete elevations of the interior of the vessel are thermally coupled to corresponding longitudinal portions of the sensor. The correspondence is incrementally continuous such that the elevations corresponding to the portions of the sensor increase from one to the other end of the sensor. The sensor may be actuated resulting in a resistance measurement indicative of the temperature detected by it. The vertical dimension of the sensor is sufficiently large such that the resistance measurement will vary in proportion to the longitudinal portion of the sensor thermally coupled to the liquid. The sensor generates an electrical signal defining a temperature signal indicative of the resistance measurement and thereby the temperature detected by the sensor. A processor is electrically connected to the sensor for receiving and measuring the temperature signal after actuation of the heater. The processor is programmed to use the temperature signal to calculate the elevation of the upper surface of the liquid in the vessel.
