Description
The Lidec level switch type L20D, designed for maritime applications, is based on the wave propagation in metal principle.
This Concept is completely static, without vibrations or moving parts. The reliability of the device is ensured by a self-monitoring function which signals electronic or transducer failures. Lidec L20D is designed to be installed horizontally (or vertically). Also, it requires no calibration as not influenced by type of fluid.
