| This table uses the double-decked four nixietubes to demonstrate the actual value of pressure and the setting value separately; The output window single line bar code demonstration output, has the pressure bound warning, may by the relay electronic contact output, the voltage pulse output, bidirectional be possible to control the silicon actuation trigger to output; The constant flow (or constant pressure) outputs, as soon as the completely automatic kneading board debugging routine, causes the system calibration only to press gently; This table uses three antijamming measures, causes the regulator to work reliably; First, uses the electro-optic isolating circuit to cause the input and the microprocessor isolates, the microprocessor and the output isolate, the power source and the input, the microprocessor, the output isolate; Second, uses the software antijamming measure, causes the software to work reliably; Third, uses the hardware procedure supervisory system, after enabling the system program receives the disturbance, the self-recovery normal work. After the practice indicated that uses above antijamming measure to be possible to enable the system software to have the very high reliability, guaranteed that the system work is stable, is reliable, the output is PID and the fuzzy control unifies, causes the manual automatic non-perturbation cut, simultaneously the power value of exports to step-by-step the output. this product widely applies in the petroleum, the chemical fiber, the plastic profession to the high temperature melt pressure survey and the control. |
