    • A sensor arrangement determines a condition and level of a liquid in a container. A first sensor has first electrodes forming a first measuring chamber communicating with the liquid and supplies a signal for determining an impedance of the first sensor and a condition of the liquid in the container. A second sensor has second electrodes forming a second measuring chamber communicating with the liquid via the first measuring chamber and supplies a signal for determining an impedance of the second sensor and a level of the liquid in the container. Electronic devices are coupled to the first and second sensors, and determine the impedance of the first and second sensors and the condition and level of the liquid in the container.
    • 传感器装置确定容器中的液体的状态和水平。 第一传感器具有形成与液体连通的第一测量室的第一电极,并且提供用于确定第一传感器的阻抗的信号和容器中液体的状态。 第二传感器具有形成第二测量室的第二电极,第二测量室经由第一测量室与液体连通,并且提供用于确定第二传感器的阻抗的信号和容器中液体的高度。 电子设备耦合到第一和第二传感器,并且确定第一和第二传感器的阻抗以及容器中液体的状态和水平。
