It can also be used as an integral part of a system for the monitoring of a continuous liquid or liquid/solid level. In addition, this specialized sensor can also be used for automated pump protection, as the measured level is directly linked to the start and stop status of the pumps.

Working Principle

The CR6211-500-5 specialized sensor uses capacitive technology to measure liquid levels with accuracy and speed. It is a microprocessor-based, dual-mode capacitive sensor that works by measuring the changes in capacitance. Capacitance is a property of a capacitor, which is a two-terminal electrical device that stores electrical energy and can store charge. In this case, the capacitor consists of two electrodes separated by a dielectric material. By measuring the capacitance of the device, the liquid level can be accurately determined.

The principle of capacitance based level measurement can be described as follows: when an electrode is immersed in a liquid, it forms an electrical double layer with the dielectric material separating the two electrodes. This double layer creates an electrical capacitance across the electrode, which can then be measured. The capacitance increases as the liquid level rises, and decreases when the liquid level falls. By monitoring this capacitance, the level of the liquid in the application can be accurately measured.

Conclusion

The CR6211-500-5 is a specialized sensor designed to provide accurate and reliable liquid level measurements in harsh and changing environments. With its advanced capacitive technology, it can be used as a non-contact level switch, pump protection, and more. This sensor has a wide range of applications and is an ideal choice for automated liquid level measurements.
