Contact-free capacitive level switch offers full media compatibility
30 November 2009
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 25mm. The device makes use of non-invasive capacitive sensor technology to achieve complete media compatibility.
The CLW sensor can be mounted on the outside of a container or vessel and is able to measure through almost any non-metallic wall material. The level switch can be easily calibrated and achieves high accuracy and reliability thanks to an additional reference electrode, which compensates for all changes in ambient conditions.
