Control system introduction | A. Chamber temperature: This equipment uses an anti-corrosion heater to heat the temperature on both sides of the chamber. The heater is equipped with a safety cover and fed back to the control system through a temperature sensor. B. Saturator temperature: It is achieved through electric heating, and the temperature varies according to the test temperature. Air pressure 0.7 0.84 0.98 1.12 1.26 1.4 Test temperature 35℃ 45 46 47 48 49 50 Test temperature 50℃ --- 61 65 70 74 --- The saturator temperature is transmitted to the control system through a temperature sensor. The control system calculates the power through PID adjustment to ensure the saturator temperature. C. Spray switch: The spray switch actually controls the on and off of compressed air. When spraying, compressed air enters the nozzle, sprays salt water, and forms mist particles. The solenoid valve opens and starts spraying. When the spray stops, the solenoid valve closes, and the compressed air no longer enters the nozzle, that is, the spray stops. D. Pressure and flow: two parameters closely related to the amount of sedimentation. E. Communication function: equipped with LAN interface F. Equipment operation indicator: indicates that the equipment is operating normally or in standby mode. G. Sound and light alarm: the alarm light is on in abnormal situations, and there is a buzzer alarm. I. Auxiliary functions: PID self-tuning function, fault alarm and cause, processing prompt function; power-off protection function, timing function (automatic start and automatic stop), fault display and self-diagnosis function. | ||
