Description

The Renke RS-ZD-N01-1S-1000 turbidity sensor employs the 90-degree scattering light method using an 860nm infrared LED, ensuring measurements are unaffected by the color of the water sample. This principle, combined with a fiber optic structure, provides strong resistance to external light interference and delivers stable, accurate readings suitable for continuous environmental monitoring.

Engineered for harsh environments, the sensor features a corrosion-resistant, passivated probe surface and a fully sealed IP68 housing. It includes a built-in temperature sensor for automatic compensation, minimizing thermal drift, and an integrated cleaning brush mechanism to reduce maintenance frequency and prevent fouling, supporting a service life exceeding two years.

Key Features

  • High-precision 90-degree scattering optical measurement principle.
  • Robust RS485 interface with standard Modbus RTU protocol for industrial communication.
  • IP68 submersible design with corrosion-resistant construction for long-term deployment.
  • Integrated automatic cleaning brush minimizes maintenance and ensures measurement consistency.
  • Built-in temperature transmitter provides automatic compensation for enhanced accuracy.
  • Infrared (860nm) light source eliminates interference from water sample coloration.
  • Factory pre-calibrated for immediate installation and use upon delivery.
  • Wide operating voltage range (DC 10-30V) with low power consumption (0.2W).

Applications

  • Continuous online monitoring of river and stream water quality for environmental agencies.
  • Effluent and influent turbidity measurement in wastewater treatment plants and sewage networks.
  • Sedimentation tank and clarifier control in drinking water treatment facilities.
  • Field research and monitoring of sediment transport in hydrological studies.
  • Precise laboratory analysis and process control in industrial water quality testing.

Frequently Asked Questions

What communication protocol does this turbidity sensor use?

The sensor uses an RS485 serial interface with the standard Modbus RTU protocol. This allows for easy integration into industrial control systems, SCADA networks, and data acquisition setups that support Modbus, enabling multi-drop communication with other devices on the same bus.

How is the sensor powered and what are the voltage limits?

The sensor operates on a wide DC voltage range of 10 to 30 volts, making it compatible with common industrial 12V or 24V DC power supplies. Its low power consumption of 0.2W ensures stable operation. Always ensure the polarity is correct when connecting the power wires within the cable.

Does the sensor require calibration before use?

No, the Renke turbidity sensor is factory-calibrated and ready for immediate use upon delivery. The integrated automatic temperature compensation and stable infrared light source ensure accurate readings without the need for user-side secondary calibration under normal operating conditions.

What is the significance of the IP68 rating and how deep can it be submerged?

The IP68 rating confirms the sensor is dust-tight and protected against continuous immersion in water. It is rated for normal operation at depths up to 20 meters, making it suitable for deployment in deep wells, reservoirs, and submerged monitoring applications without risk of water ingress damaging the electronics.

What is the purpose of the automatic cleaning brush?

The built-in automatic cleaning brush periodically wipes the optical window of the probe to prevent biofilm growth, algae accumulation, or mineral scaling. This feature is critical for maintaining long-term measurement accuracy and reducing maintenance frequency in biologically active or high-fouling water bodies.
