Capacitive Point Sensors: Enhancing Liquid Level Detection for Diverse Applications
What Are Capacitive Point Sensors?
Capacitive point sensors detect a single (i.e., point) level of liquid levels in containers without direct contact with the liquid itself. These sensors operate based on the principle of capacitance. They form two electrodes: one on the sensor and the other on the container wall. Changes in capacitance occur due to fluctuations in liquid levels. These changes are converted into switching signals that indicate specific levels, such as “Empty” or “Full.”
Because they operate with non-metal containers (plastic, glass, ceramic), capacitive sensors can be used in a wide range of settings. By employing a non-invasive method, they minimize contamination risks and offer a maintenance-free solution for managing fluid levels and preventing overfill or underfill situations.
Key Features and Advantages
-
Non-Contact Measurement: The sensor measures liquid levels through the container wall, making it an ideal solution for applications involving sensitive fluids, where avoiding contamination is crucial.
-
Multiple Applications: Various industries, including medical, food, environmental protection, and industrial automation, use capacitive point sensors in multiple applications.
-
Cost-Efficient: Their low cost and maintenance-free operation make them an ideal choice for applications requiring reliable and continuous fluid monitoring.
-
Adaptable Installation: You can attach the sensor externally along the vertical side of a container, allowing it to provide different measurement points like ‘Empty,’ ‘Full,’ or ‘Near Full.”
