PH automatic controller, as an intelligent water quality management device, plays a crucial role in multiple industries. With the continuous advancement of technology and the expansion of applications, it will play a more important role in the field of water quality management in the future.
The PH automatic controller mainly consists of sensors, secondary meters, automatic dosing system, and control system
1. Sensor: responsible for measuring the pH value of water quality and converting it into an electrical signal to transmit to the secondary meter. Sensors typically consist of a glass electrode and a reference electrode. The glass electrode is sensitive to hydrogen ions, while the reference electrode provides a stable potential.
2. Secondary table: Process and display data based on received signals, and issue instructions to the automatic dosing system through preset control logic
3. Automatic dosing system: Automatically adjust the dosage according to instructions to control the pH value of water quality.
4. Control system: Programmable logic controllers (PLCs) are commonly used as regulators, which can simultaneously input multiple signals such as pH value, input flow rate value, storage tank liquid level, etc., and calculate the required neutralizing agent metering value through certain algorithms to accurately control the dosage.
Functional characteristics of PH automatic controller
1. Real time monitoring: It can monitor the pH value of water quality in real time to ensure the continuity and stability of the production process.
2. Automatic adjustment: Automatically adjust the dosage according to the preset control range, achieving precise control of the pH value of water quality.
3. Alarm function: It has multiple alarm functions, such as over limit alarm, fault alarm, etc., to ensure that relevant personnel can be notified in a timely manner for handling in case of abnormal situations.
4. High intelligence: Adopting advanced automatic control systems and precise sensor technology to achieve a high degree of automation and intelligence.
PH automatic controllers are widely used in various industries such as industry, electricity, agriculture, medicine, food, and environmental protection.
1. Water treatment: Used in sewage treatment and drinking water purification to regulate the acidity and alkalinity of water to meet discharge standards and health and safety requirements.
2. Chemical industry: In chemical reactions, pH value is crucial for reaction rate and product selectivity. The pH controller ensures that the reaction is carried out under optimal pH conditions to improve yield and quality.
3. Food processing: During fermentation, soy sauce production, and other processes, it helps maintain a suitable pH level to ensure the flavor and safety of the product.
4. Agriculture: In hydroponics and soil management, it is used to monitor and regulate the acidity or alkalinity of soil or solutions to ensure a suitable growth environment for plants.
