PRECISION CONTROL SYSTEM ZERO thermostats

摘要

The system control precision zero-thermostat comprising a temperature sensor associated with an amplifier block reverse polarity power for a thermoelectric module, characterized in that it comprises three sensors for measuring the temperature in the inner volume of the chamber with the working medium, connected with their outputs to the normalizing signal amplifiers with sensors which are connected to the analog-digital converter that converts a digital code the measured values ​​of temperature sensors and their outputs connected to the inputs mic roprotsessora performing functions of digital signal processing and control system operation process and the formation of control actions to analog converters, signaling module interface converter for the communication with external devices and polarity switching modules, the outputs of which are connected with current regulators inputs, voltage controlled that form the stabilized currents power to the thermoelectric modules, the user interface, the output of which is connected to the block with conjugation which its second input connected to the output interface converter, two differential thermocouples, the signals from the reference and the reference junctions are applied to two input measuring module tilt angle, the other input connected to the device reference difference with the output plug to the module signal and the inverter interface to another interface converter connected to the pulse reference device which generates current pulses flowing through the first inductor and causes AC
