Digital Temperature Controlled System

For the investigation of continuous and discontinuous control loops.
Unipolar heat source (max. 20 W for 20 V) with temperature sensor, thermal protection switch, fan motor and "throttle flap", built into a transparent air channel. With two integrated power amplifiers for heater and fan, thus ideal for control systems with multi input control (Fuzzy). Three digit 7-segment display for temperature in °C including trend indicator for the temperature change (rising or descending). Two possibilities for controlled system disturbance:

• via fan motor, internally with speed setter 1...10 or from an external signal source max. 20 V
• via "throttle flap", position 0 (closed) up to position 4 (open)
