RT 450.01

Controlled System Module: Level

Technical Description

The RT 450.01 is operated with water as the working medium and consists of a clear plastic liquid level tank. The tank is set up in such a way that it is hermetically sealed if all taps and valves are closed. This enables experiments to be performed in the tank under internal pressure. For safety, the liquid level tank is fitted with a pressure relief valve and is enclosed in a protective cover, also of clear plastic. The tank has fittings for attaching a pressure transducer (RT 450.31) or a level gauge (RT 450.35). It is installed in the basic RT 450 module. A control valve (e.g. RT 450.21) and a controller (RT 450.10) complete the control loop.

Learning Objectives / Experiments

- Setting up a level control loop
- Comparison of different sensors for liquid level measurement
- Liquid level control against an air cushion
- Liquid level / flow cascade control (with RT 450.02)

Features

* Main element for setting up a liquid level control loop
