RT 578 Multi-Process Control Trainer Show data sheet (pdf file)
Technical Description
This control trainer is a comprehensive unit featuring only industrial components. It contains a transparent tank for liquid-level and pressure control, a corresponding pipe for flow control, and a two-circuit system with a plate heat exchanger for temperature control. Alternatively, a pneumatically operated control valve or a speed-controlled pump are used as actuator. The parameters of the digital controller can be adjusted over wide ranges so that a large number of different process conditions can be investigated. Electronic sensors measure the individual process values. A three-channel recorder with current inputs is included for recording the control behaviour over time.
Software for the process visualisation RT 578.20 and RT 650.12 Profibus card are available as an accessory.
