The CQF capacitive level sensor detects liquids through container walls and through direct contact with the liquids. The measurement principle compensates for foam, moisture and deposits. This ensures that the CQF only detects the liquid in the container – nothing else. For standard applications, the sensor is ready for operation without additional settings. For challenging applications, it can be taught-in quickly and easily using the cable. The mounting set offers different installation options, making the CQF is well-suited for countless customer applications.
