Description

The RS-CH-N01-2-EX utilizes the fluorescence excitation method to detect chlorophyll-a concentrations in water, providing a direct indicator of phytoplankton biomass and water trophic status. Its non-membrane, reagent-free design ensures stable, low-maintenance operation suitable for long-term deployment in rivers, lakes, reservoirs, and aquaculture ponds.

The sensor’s robust plastic housing and IP68 rating protect the internal electronics from harsh aquatic environments, while the integrated automatic cleaning mechanism periodically removes debris and biofilm from the optical window. This combination of features delivers reliable, real-time data with minimal manual intervention, making it ideal for environmental monitoring networks and research studies.

Key Features

  • High-precision fluorescence detection principle for accurate chlorophyll-a quantification.
  • Automatic mechanical cleaning system minimizes maintenance frequency and data drift.
  • Industrial-grade RS485 interface supporting Modbus-RTU protocol for system integration.
  • Full IP68 submersible construction ensures reliability in demanding underwater applications.
  • Built-in temperature compensation corrects for environmental variations, enhancing accuracy.
  • Standard 3/4" NPT mounting threads facilitate easy installation in pipelines or sensor buoys.
  • Wide operating voltage range (10-30V DC) compatible with standard field power supplies.
  • Corrosion-resistant materials selected for longevity in fresh and saltwater environments.

Applications

  • Continuous chlorophyll monitoring in reservoirs and drinking water source protection programs.
  • Algal bloom prediction and trophic status assessment in lakes and coastal marine environments.
  • Water quality management and optimization in intensive aquaculture and fish farming operations.
  • Long-term ecological research and environmental impact studies in riverine systems.
  • Integration into multi-parameter water quality monitoring buoys and fixed station networks.

Frequently Asked Questions

What is the communication protocol of the RS-CH-N01-2-EX sensor?

The sensor communicates exclusively via the RS485 serial interface using the Modbus-RTU protocol. This industrial-standard protocol allows for easy integration with PLCs, SCADA systems, and data loggers that support Modbus, enabling multi-drop network configurations for monitoring multiple sensors on a single bus.

How does the automatic cleaning function work and how often does it activate?

The sensor features an integrated mechanical brush that automatically cleans the optical measurement window at programmable intervals. This prevents biofilm and debris accumulation, which can cause signal drift. The cleaning interval is typically configurable via the Modbus interface to balance maintenance needs with power consumption for the specific deployment environment.

What is the maximum depth and pressure this sensor can withstand?

The sensor housing is rated IP68, meaning it is waterproof and submersible up to 20 meters depth. It can withstand a maximum pressure of 0.6 MPa (approximately 6 bar). It is suitable for deployment in deep monitoring wells, on submerged buoys, or in pressurized pipeline applications within these limits.

Can this sensor be used in saltwater (marine) environments?

Yes, the sensor's plastic housing and internal components are designed to be corrosion-resistant, making it suitable for both freshwater and saltwater applications. The automatic cleaning function is particularly beneficial in marine environments to combat faster biofouling rates on the optical surfaces.

What power supply is required, and is the cable length customizable?

The sensor operates on a wide-range 10-30V DC power supply, commonly available from industrial power sources or solar-charged batteries in field deployments. The standard cable length is 5 meters, but longer custom cable lengths can typically be specified at the time of order to suit specific installation requirements.
