Product Description And Features

Capacitive liquid level sensors offer several key advantages, making them highly effective in liquid level monitoring and control applications. They are capable of detecting a wide range of liquids, including water, oil, and chemicals, without being affected by the liquid’s conductivity. This versatility makes them suitable for a variety of industrial and commercial applications.

One of the major benefits of capacitive liquid level sensors is their non-contact detection capability. They can measure liquid levels through the container walls without direct contact with the liquid, thereby avoiding issues related to corrosion or contamination and extending the lifespan of the equipment. Additionally, these sensors offer high precision and sensitivity, enabling the detection of even the slightest changes in liquid levels, which is essential for applications requiring accurate level control.
