Detecting the level using conductive electrodes is a simple, robust method that offers a wide versatility in a large number of processes. They can be installed both vertically and horizontally and the same equipment can contain up to five electrodes that the user adapts to the distance he needs. Unit models are often used in borehole surveys.
The conductive electrodes must be connected to the appropriate level relay depending on the characteristics of the application. There are numerous models that, combining them, cover a wide range of detection and control possibilities. The choice of the ideal relay provides advantages such as electrical safety and a solid control maneuver.
For control maneuvers of a single level point or for common filling or emptying controls, it is convenient to use a compact system that combines the electrodes with the relay. Save space, control elements, wiring and installation time.
