3、 Typical application cases

Case 1: Multi parameter linkage control of biochemical tank in municipal sewage treatment plant

1. sceneMonitor the DO (2-4 mg/L), pH (6.5-8.0), temperature (15-35 ℃), and reflux flow rate of the biochemical tank, and link the aeration fan, dosing pump, and reflux pump to ensure the efficiency of nitrogen and phosphorus removal.

2. configuration

• Controller: 202581 (pH/ORP, conductivity, dissolved oxygen module, 4-channel PID).

• Sensors: JUMO dissolved oxygen electrode, pH electrode, Pt100 temperature transmitter, electromagnetic flowmeter (pulse output).

• Executors: Aeration fan (PID1), alkali dosing pump (PID2), reflux pump (flow interlock).

3. control logic

• DO<2 mg/L → PID1 increases fan frequency; PH<6.5 → PID2 starts alkaline dosing; Temperature>35 ℃ → Alarm and linkage cooling.

• Paperless recording of DO/pH/temperature trends, Ethernet upload to SCADA, email push of over limit alarms.

4. effectThe effluent compliance rate has been increased to 99.5%, aeration energy consumption has been reduced by 22%, and maintenance manpower has been reduced by 60%.

Case 2: Pharmaceutical purified water system - full process monitoring of water quality

1. sceneMonitor the conductivity (≤ 1 μ S/cm), pH (5.0-7.0), temperature, and tank level of RO reverse osmosis and EDI modules to ensure GMP compliance and water quality stability.

2. configuration

• Controller: 202581 (conductivity, pH module, 2-channel PID).

• Sensors: JUMO inductive conductivity sensor, pH electrode, input type liquid level transmitter.

• Executors: RO flushing valve (triggered by conductivity exceeding the standard), EDI power supply (PID regulation), liquid level interlock water replenishment valve.

3. control logic

• RO water conductivity>1 μ S/cm → automatic flushing; EDI effluent pH deviates from 5.0-7.0 → PID regulates power supply current.

• Paperless recording of key parameters, supporting data export for GMP audit tracking.

4. effectThe water quality qualification rate is 100%, the flushing frequency is reduced by 18%, and the audit traceability efficiency is improved by 80%.

Case 3: CIP cleaning of food and beverage - temperature/concentration/liquid level linkage control

1. sceneThe CIP station of the dairy factory monitors the temperature of the cleaning solution (60-80 ℃), alkali concentration (2% -5%), and tank liquid level, and links heating, dosing, and inlet valves to ensure cleaning effectiveness and equipment safety.

2. configuration

• Controller: 202581 (conductivity, temperature module, 2-channel PID).

• Sensors: Contact conductivity sensor (for concentration measurement), PT100 temperature transmitter, capacitive level switch.

• Actuators: heater (PID1), alkali dosing pump (PID2), inlet valve (liquid level interlock).

3. control logic

• Temperature ＜ 60 ℃ → Heating; >80 ℃ → Stop; Concentration<2% → Add medication; Liquid level ＜ 20%/＞ 90% → Alarm and close valve.

• One click switching of cleaning program on touch screen, paperless recording of cleaning curve.

4. effectCleaning temperature fluctuation ± 1 ℃, concentration control accuracy ± 0.2%, no dry operation/overflow accidents.

4、 Selection and expansion suggestions

1. Module matchingSelect the analysis module based on parameter requirements (such as pH+conductivity+dissolved oxygen), with universal input covering auxiliary signals such as temperature and pressure.

2. Communication ExpansionWhen remote monitoring is required, Ethernet and web servers are enabled, Modbus RTU is adapted to PLC/SCADA, and email alarms improve response speed.

3. Load adaptationWhen the output load is greater than 5 A, an intermediate relay should be added to protect the controller contacts.
