Product Description

Advanced PID Controller Trainer 

The tank contains PT-100, a Thermocouple whose resistance varies as the temperature varies and there by varying the output voltage. This analog variation is sensed by the Thermocouple sensor and gives a corresponding, amplified output to the ADC. Tank also contains a stirrer, to keep the temperature of water uniform. Analog to Digital Converter converts the analog signal from thermocouple and displays the temperature Digitally on the display. Micro controller Circuit fetches the digital signal from the ADC, when capture code "#01M" is provided by the software (XTALK). The input format for acquiring the data from ADC to the micro controller is provided by the software from computer through serial cable "Rs232". DAC accepts the input data format as "#02XBBB". This "BBB" is the 12 bit data for controlling the DAC output voltage provided by the computer through micro controller. The DAC output voltage (DC) controls the output voltage (AC) of the TRIAC control circuit. The AC output voltage of the TRIAC controls the heating elements. This heating is sensed by the PT-100 & gives the analog signal to the thermocouple sensor and thus forms a close loop circuit.
