Application Scenarios

2) Product features

- Measurement: inductive (digital) conductivity sensor measuring conductivity (0–2000 mS/cm), TDS (0–130,000 mg/L), salinity (0–80 g/L) and concentrations for common acids/bases (e.g., HCl 0.00–17.98% & 20.01–39.07%, HNO3, NaOH, H2SO4, KOH, NaCl) plus temperature (-40 to 150 °C).

- Sensor technology: digital inductive conductivity sensor for fast response, high precision and long service life.

- Outputs & integration: RS485 (Modbus), two isolated 4–20 mA outputs, two relays (5 A, 250 VAC / 5 A, 30 VDC) for high/low alarms or control.

- Data functions: on-device data recording and history curve review for trend analysis.

- Robust design: wide power range for global use and IP65 enclosure.

3) Product value

- Enables continuous, accurate monitoring and control of acid/base concentrations to maintain water quality and process consistency.

- Improves process safety by providing alarm outputs and real-time data for quick corrective action.

- Reduces maintenance and downtime via inductive sensor durability and less frequent sensor replacement/calibration.

- Facilitates automation and traceability through Modbus and 4–20 mA integration and onboard data logging.

4) Product advantages

- Inductive (non-contact) conductivity measurement: long lifetime, low fouling and minimal maintenance compared with electrode sensors.

- Digital sensor performance: fast, stable and precise concentration readings.

- Wide measurement ranges that cover dilute to concentrated solutions for many acids and alkalis.

- Multiple output options and alarm relays for easy integration into DCS/PLC systems and local control schemes.

- Compact, weather-protected (IP65) unit with broad supply voltage compatibility for flexible installation.

5) Application scenarios

- Thermal power plants: monitor and control pickling, boiler water treatment and regeneration liquids.

- Chemical industry: online concentration control in production, mixing and regeneration processes.

- Water treatment and ion-exchange systems: monitor regenerant concentration for high-purity water production.

- Industrial process lines requiring continuous acid/base concentration control, safety alarm monitoring and data logging.

- Any potable or process water application where accurate, low-maintenance conductivity-based concentration measurement and integration with automation systems is required.
