Contact-Free Capacitive Level Switch Allows For Complete Media Compatibility

Sensortechnics’ new CLW series detects point levels of liquids and granular or pulverised materials without contacting the media. The user can easily adjust a high and low switch point with a hysteresis of less than 25 mm. The CLW device uses a new non-invasive capacitive sensor technology and allows for complete media compatibility and sterility. Due to its miniature size these level switches can be perfectly integrated into OEM devices.

The CLW 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 switch is highly flexible and can be easily calibrated to measure to the desired levels, media and application set-up. The CLW series achieves a very high accuracy and reliability due to an additional reference electrode which compensates for all changes in ambient environmental conditions such as temperature and humidity. Additionally, Sensortechnics can also provide continuously measuring level sensors based on the same contact-free capacitive technology.

Important features of the new CLW series are:

• Contact-free capacitive sensor technology
• Point level monitoring of liquids, granular or pulverised materials
• Adjustable hysteresis of less than 25 mm
• Miniature size for easy integration into OEM devices

Due to its new contact-free capacitive technology Sensortechnics’ CLW level switch can be used in many level monitoring applications within medical, laboratory and analytical technology, chemical and pharmaceutical industries, also biotechnology as well as food and beverage.
