The RT 450.04 controlled system module is a board-mounted ready-to-install element. In conjunction with other modular control components, it enables temperature control systems with different characteristic features to be constructed and investigated.
The assembly panel is mounted on the carrier frame of the base system RT 450. The main elements of the controlled system module are: an electric heater installed in a section of pipe, and a plate heat exchanger between the primary and secondary water circuits. The heater can either be operated by a switching controller and so act as the control loop actuator, or can operate in continuous duty as a pure energy source. In operation as a continuous controller, with the heater as the energy source, a choice of two different valves (pneumatic or electric) can be used as actuators in the primary circuit.
For safety, the heater features a thermostat and a device to protect it from running dry.
The primary circuit (with heater) is connected by pipelines to the water supply of the base system RT 450, while the secondary circuit requires a laboratory water supply for cooling. Counter-flow or parallel-flow cooling is possible. The connection to the laboratory network is made by quick-release couplings and hoses.
Extensive technical documentation is provided for the RT 450 complete system. The instructional documents detail the technological fundamentals and provides a step-by-step guide through the set tasks and exercises.
