Level Control Training System | NexuMation 61
The Level Control Training System NexuMation 61 is an experimental unit for learning control engineering fundamentals. This level control training system has a transparent 1L level-controlled tank, a 38L storage tank, and a speed-controlled pump rated 6W, 25L/min and 2m max head. Level is measured by a pressure sensor. Disturbances are generated by an electromagnetic proportional valve. LabVIEW software connects via USB under Windows 10.
The Level Control Training System NexuMation 61 offers a way to learn the basic fundamentals of control engineering. This level control training system uses a transparent level-controlled tank fed by a speed-controlled pump. The liquid level is measured using a pressure sensor.
Product Overview
The level control training system feeds a transparent level-controlled tank from the storage tank. A speed-controlled pump does the feeding. The liquid level is measured using a pressure sensor.
The sensor output signal is sent to the software controller. The controller’s output signal influences the speed of the pump motor. This changes the delivery flow rate.
A solenoid valve in the tank outlet can be activated by the software. This allows the influence of disturbance variables to be investigated.
The software is designed in LabVIEW. It is an integral part of the training system and embodies the principle of hardware/software integration (HSI). It enables experiments to be conducted and evaluated in a user-friendly manner. The link between the experimental unit and the PC is made via a USB port. The well-structured instructional material sets out the fundamentals. It provides a step-by-step guide through the experiments.
