Adjustment System
| Project | Illustrate |
| Adjustment method | Forced circulation ventilation, balanced temperature regulation. The control system controls the output of the heater according to the temperature point set by the system through the result of PID automatic calculation output, and finally achieves a dynamic balance.
|
| Circulation device | The built-in air-conditioning room, circulating air duct and long axial flow fan improve the air flow and heating capacity by improving the agitation airflow of the air, and greatly improve the temperature uniformity of the test chamber. |
Control System
| Project | illustrate |
| Controller | 7-inch PLC LCD touch programmable controller |
| Touch high-definition screen | The fixed conditions and program conditions can be set arbitrarily, the Chinese screen can be set, and the curing test name and serial number can be set. |
| Settable time range | 0—999H59min. |
Programmable mode
| At the same time, 120 groups of programs with different conditions can be set. In any group of programs, the work can be divided into 1200 segments, and the number of segments can be arbitrarily intercepted to execute the cycle, or the periodic cycle of any segment or group can be performed. |
| In each group of programs, up to 1200 different temperature and time sections can be set (each section can be set up to 999h59min). 120 groups of programs can be connected in series at will, and the maximum number of sections can be cycled up to 999 times. | |
| Safety | With a power-off memory device, the remaining programs can continue to be executed when the power is restored, and the machine can be reserved to execute the start-up and machine running time. |
| Control | Rising and cooling can be used for slope control and curve control, and has the function of self-correcting temperature and humidity reference points. It has the function of PID automatic calculation, which can reduce the convenience brought by manual setting. |
| Communication function | U disk interface, RS-232 interface, mis operation hardware lock, random computer communication software |
| Set up | Touch setting, direct display of position, all conditions are completely automatically locked by microcomputer |
| Call the police | If there is an error in the setting or operation, a warning signal will be provided |
| Output | The controller has a recording signal port output, which can be connected to a temperature and humidity recorder and output a recording curve |
| Interface | With standard RS-232 communication interface, long transmission distance, can be connected to PC for control and recording. |
