PH value automatic controller

1PH value automatic controllerrole

In both human life and industrial production, pH control is an extremely important process that affects and influences many procedures; At the same time, with the strengthening of human awareness of environmental protection, the control and requirements for environmental protection are becoming higher and higher. Environmental protection is increasingly valued, and the control of wastewater discharge in industrial production processes is becoming stricter. Various biochemical indicators are included in supervision, and pH value is a very important indicator among them; If the pH value is too acidic or too alkaline and discharged into rivers, lakes, and seas, it will have irreversible effects on the water body and aquatic ecology. Traditional manual monitoring of pH value is time-consuming and labor-intensive, and the control accuracy cannot be guaranteed, so it will gradually be replaced by automatic control. At the same time, due to the use of high-precision and long-life pH meters to measure pH values, the accuracy of automatic control will reach a new height, which is extremely beneficial for production monitoring in pharmaceutical, chemical, electroplating and other factories.

IIPH value automatic controllerthe principle of

By inserting and installing a high-precision pH sensor into the measured liquid, the pH value of the liquid is accurately measured, and the corresponding signal is transmitted to the WK quantitative controller. The display, operation, and control are completed in the WK quantitative controller. According to actual requirements, a stable pH range is pre-set in the WK controller. The WK quantitative controller automatically controls and outputs a signal based on the pH sensor signal to adjust the dosage of acid or alkali solution. After reaching the set range, the dosage of acid or alkali solution is stopped, thereby stabilizing the pH value within the required value and range.

IIICharacteristics of

1PH sensors are the focus of control, therefore imported types are used, with high measurement accuracy, long service life, and accurate control;

2Real time pH value display, conducive to monitoring; Convenient for personnel to monitor at any time;

3The control value can be set arbitrarily, and the value and range can be set according to requirements;

4High precision control and display, with a display multiplier of 0.01;

5Combination of manual and automatic: In automatic mode, no personnel operation is required, and fully automatic control is completed; In manual mode, acid or alkali solution can be manually added according to actual requirements;

6Emergency stop operation for feeding, in case of emergency, manual one click operation for emergency stop feeding control, effective in both manual and automatic states;

7PH value and temperature can be monitored simultaneously, and the pH electrode can automatically calibrate according to temperature;
