Temperature Regulation & Control Trainer Model PCU 056
Temperature Regulation & Control Trainer Model PCU 056
Sci-tech Temperature Regulation & Control Trainer Model PCU 056 consists of four clearly differentiated parts :
● Hydraulic circuit consisting of a lower tank and an upper tank, one centrifugal pump, one flow-meter, three open / closed solenoid valves, one motorized control valve and drainage valves.
● Stirrer, electric heating resistance and temperature sensor (Thermo coupler)
● Digital PID controller with universal input. (Honeywell or equivalent make)
Item Description
For tests of temperature control the liquid is pumped from the lower tank by means of a pump, the fluid successively going through the flow-meter, the solenoid valve, the motorized control valve and the upper tank. The upper tank has a variable level spillway, two descending lines with solenoid valves of different discharge factors and a third normal drainage valve.
The control console has a power supply (for the performance of the equipment in manual mode without computer), a PID controller and a box only accessible for the teacher, where failures and breakdowns can be simulated. The system enables to control the temperature of a continuously stirrer tank having an electric resistance.
The tank is fed with water for which the flow rate and the temperature are known, and is heated with an electric resistance the power of which can be adjusted by means of a rheostat. The liquid temperature in the tank is measured by means of a sensor.
