Level controllers
Level controllers
This control device, in the form of a level controller, enables level control of conductive liquids such as rainwater, tap water, or condensate. This device is capable of monitoring four levels simultaneously.
With two independent stages, the level controller enables parallel monitoring of the minimum and maximum liquid levels and the control of two different actuators (e.g. a filling valve and a pump).
Yes, customised designs are available on request. Please note that due to the planning and implementation costs involved, we can only produce customised designs for orders with a minimum value of €500.00.
Two-point controllers operate with two states: on and off. Three-point controllers add a neutral intermediate state. In contrast, continuous controllers, which are designed to reach and maintain the setpoint quickly and accurately, operate with less overshoot. The basic types of continuous controllers are P, I and D controllers. The P controller quickly brings the actual value closer to the setpoint, but has a permanent control deviation that can be compensated for by combining it with an I controller. The I controller integrates the control deviation over time to compensate for it, but is slow. A PI controller combines these characteristics, but responds slowly to sudden changes. This is where the D controller comes in, quickly correcting even small deviations. Since a pure D controller does not recognise a constant deviation, it is combined with P or PI controllers to improve response time. A PID controller combines all three algorithms to respond quickly to both large and small control deviations and eliminate permanent deviations.
