Turbidity Sensor Turbidity Sensor at Sale Company
Product Overview
- Model ZDYG-2088-01 online digital turbidity sensor from BOQU Instrument.
- Uses infrared light scattering (double-beam) and infrared absorption to convert scattered light to electrical signals, then performs analog/digital processing.
- Designed for continuous in-line turbidity measurement with digital RS485 (Modbus RTU) output; powered by DC 12V.
- Rugged construction (SUS316L + PVC body options, fluorine rubber O‑ring) and IP68/NEMA6P protection.
Product Features
- Measurement range options: 0.01–100 NTU or 0.01–4000 NTU; resolution 0.01 NTU.
- Accuracy: ±1% of reading or ±0.1 NTU (whichever is greater). Operating temp 5–60°C; inlet pressure ≤0.4 MPa.
- Uses ISO7027 infrared scattering method to eliminate color interference; double-beam design for good repeatability and stability.
- Built-in automatic cleaning brush with configurable cleaning intervals (very low maintenance).
- Self-diagnosis capability and standard digital output; sample and slope calibration supported.
- Communication: RS485 Modbus RTU; standard 10 m cable (extendable to 100 m).
Product Value
- Provides reliable, real-time turbidity data to support process control, regulatory compliance and water quality decision-making.
- Reduces maintenance workload and downtime through automatic cleaning and durable materials.
- High measurement stability and anti-interference performance lower false alarms and need for manual checks.
- Easy system integration via Modbus/RS485 and stand-alone digital output options, enabling fast deployment in monitoring networks.
- Suitable for both fresh and seawater installations (sea-water type construction available).
Product Advantages
- ISO7027-compatible infrared technique and double-beam detection minimize color/optical interference and improve accuracy.
- Wide dynamic range (up to 4000 NTU option) covers both low-turbidity potable water and high-turbidity industrial streams.
- Robust, corrosion-resistant materials and IP68 rating for long-term field use.
- Automatic cleaning brush and self-diagnostics lower lifecycle costs and ensure stable readings.
- Standardized digital communication (RS485 Modbus RTU) and long cable options for flexible networking.
Application Scenarios
- Online turbidity monitoring at drinking water treatment plants (inlets, sedimentation basins, filter outlets).
- Sewage and wastewater treatment plants for process control and effluent monitoring.
- Industrial process water and waste streams where turbidity affects product quality or treatment performance.
- Coastal or marine applications using the seawater-compatible version.
- Remote or distributed monitoring systems requiring robust sensors with digital communications.
