Sensortechnics’ CLC Series uses a contact-free capacitive sensor technology to continuously measure the fill level of liquids as well as granular or pulverized materials. The miniature sensor can be mounted to the outside of a container or vessel and is able to measure through almost any non-metallic wall material. The level sensing range of the standard device is up to 10 cm (4 inch) which can be enlarged in special multi-sensor configurations. The non-invasive design, with no contact between the sensor and the fluid, eliminates all media compatibility and sterility issues. The user can easily calibrate the sensor to measure to the desired levels, media and application set-up. An additional reference electrode which compensates for all changes in ambient environmental conditions such as temperature and humidity. As an optional safety feature the sensor can be supplied with an extra sensing pad to detect if a container is actually present or not. The CLC sensor offers an analog voltage output as well as a digital interface.
