Automatic adjustment is performed by the pneumatic membrane valve to control the amount of steam in the cooling water or through the heat exchanger so that the temperature of each zone is controlled.
(0-24VDC) to the solenoid valve, the solenoid valve will be electronic control signal (0-24VDC) into gas control signal (20-100KPa), and finally the input voltage signal by the PID operation, the programmable controller output standard electronic control signal (0-24VDC)
As a man-machine interface, the host computer can monitor the running status and various parameters of the sterilization process in real time, provide the alarm, historical trend chart and data file report, and can set the PU value by the operator. The computer calculates the temperature
Programmable controller on the one hand the input and output data processing, PID operation, on the other hand will be a variety of signals into the host computer.
The temperature of the temperature by the Pt100 platinum thermal resistance and temperature transmitter into a 4-20mA signal into the programmable controller, the temperature of the pump pressure through the distributor and solenoid valve into the pressure transmitter into a 4-20mA signal
