Completely contactless level detection with continuous measurement

A key advantage of the new LCPB sensor generation is its ability to detect a wide range of media, including liquids, granules, and powdered materials. The capacitive-based sensors offer a high degree of accuracy and are virtually insensitive to external interference. In addition, the sensor sensitivity can be customised so that even media with challenging physical properties, such as oils or certain solids, can be reliably detected. The standard sensors are suitable for a variety of media and applications. EBE's capacitive technology even allows for a simple solution in special fields of application: the sensitivity of the sensors can be customised. This means that cost-effective capacitive level sensors can be used even in unfavourable applications.

Continuous measurement with a compact design

With the LCPB level sensors it is now possible to continuously measure even larger filling heights with a single sensor. So far, cascading switches have usually been used for flat non-contact measurements. However, switch solutions on the outer wall of the tank are very complex due to the required cabling and at the same time not very accurate. Alternative float solutions with integrated reed switches require mechanically moving parts that wear over time and come into contact with the medium. The sensors from EBE sensors + motion offer a reliable, compact, and cost-effective solution: the sensor technology is integrated on a printed circuit board and can be mounted outside the tank. Thanks to their high sensitivity the level sensors can measure precisely even through tank walls with a thickness of up to 8mm (0.3”). Measurement is possible despite an air gap between the tank and the sensor. Fill levels of up to 10cm (4”) can be implemented with the LCPB standard sensor, but longer measuring ranges can be realised on customer request.

Easy testing for end users

To further facilitate integration, EBE offers an evaluation kit that allows engineers to test the sensors under real operating conditions. The intuitive software of the kit enables quick commissioning and visualisation of the measured values without the need for complex hardware or interface adjustments. The measurement results can be analysed, stored, and further processed directly, which enables efficient evaluation and implementation in existing systems.
