RT 450.03 Controlled System Module: Pressure Show data sheet (pdf file) Print page
Technical Description

  The RT 450.03 controlled system module is a panel-mounted ready-to-install element. In conjunction with other modular control components, it enables pressure control systems with different characteristic features to be constructed and investigated.


  The panel is mounted on the frame of the base module RT 450. RT 450.03 consists of two steel pressure tanks and is operated with compressed air as the working medium. Each tank is fitted with a manometer and a safety valve. One tank also has a drain valve. Both tanks can be fitted with a pressure sensor. The tanks are interconnected by a vent valve and can therefore be connected in series. This makes it possible to represent both first and second order pressure control systems.


  The RT 450 base module supplies the controlled system module with its working compressed air. Pneumatic hoses with quick-release couplings connect all the modules to a pressure control loop.

Learning Objectives / Experiments

- planning, setting up, testing, optimising and

  assessing pressure control loops with different

  objectives and components
  * constructing a 1st order pressure control system
  * constructing a 2nd order pressure control system
- design and function of
different instrumentation

  and control components
- technical terminology and
symbols in industrial

  control engineering
- practical exercises: Implementing process and

  signal lines
- commissioning and troubleshooting of process

  engineering systems


* Main element in constructing a pressure control

* Rapid installation into the RT 450 base module by

  modular panel assembly
