摘要： Systems and methods for monitoring a liquid level within an interior of a container positioned on a heating assembly are provided. A method includes calculating a temperature change within the interior of the container during a predetermined time period, and determining whether a heating element of the heating assembly is on. The method further includes outputting an error signal to an indicator when the temperature change is negative and the heating element is on.

摘要： The aim is to achieve a particularly robust and reliable embodiment of a filling level sensor with several thermoelements for measuring the filling level of a liquid in a receptacle. This is achieved in that the thermoelements are arranged in parallel with one another and extend from the bottom upwards. The thermoelements are of different heights so that, depending on the filling level, one part of the thermoelements is flooded and another part is not. This can be used to derive information regarding the filling level.

摘要： A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.

摘要： A radiator detecting device of the present invention includes a radiator cap, a sensing unit, a circuit device, a warning device, and an adjusting means. One end of the sensing unit connects to the radiator cap, and another end extends toward a direction away from the radiator cap. The circuit device has a circuit board. The circuit board includes a control circuit for detecting a state of the sensing unit, and the sensing unit selectively makes the control circuit generate a suggestion signal. Once receiving the suggestion signal generated by the control circuit, the warning device generates a warning signal. The adjusting means is used for adjusting a length of the sensing unit received in the radiator. Said sensing unit can be moved with respect to the radiator between a first position and a second position. Thereby, the sensing unit can fit different depths of different radiators.
