NBL-WQ-FUV-200 Online Full-Spectrum Multi-Parameter Sensor Product Overview

NBL-WQ-FUV-200 is a multi-parameter sensor developed by NiuBoL for online continuous water quality monitoring. It integrates a micro fiber optic spectrometer, pulsed xenon lamp and adaptive algorithm. Without any reagents, it can capture the full-spectrum absorption characteristics of water bodies in the 200-800nm range in real time.

By comparing the characteristic absorption peaks of different pollutants (such as organic matter, chromaticity factors), the sensor can accurately quantify multiple water quality parameters. More importantly, its unique algorithm pre-compensates for the interference of suspended particles of different particle sizes, making it particularly suitable for water environments with certain turbidity such as surface water, sewage plant process monitoring and industrial discharge outlets. The sensor adopts 316L stainless steel material and IP68 protection level, meeting various harsh installation requirements such as submersible and pipeline types.

NBL-WQ-FUV-200 Online Full-Spectrum Multi-Parameter Sensor Core Technical Advantages

1. High-Precision Optical Engine, Stability Originates from Underlying Design

• Pulsed Xenon Lamp Light Source: Compared with traditional LED or halogen lamps, xenon lamps have high luminous intensity, wide spectral range, long life and no preheating, ensuring sufficient energy in ultraviolet to infrared bands, low temperature drift and low attenuation.

• Full-Spectrum Acquisition: Not single-point or dual-wavelength measurement. Continuous spectral analysis can effectively identify changes in water body composition and avoid the defects of single-wavelength measurement being easily interfered with.

• Spectral Calibration: Full-spectrum response curve calibration is completed before leaving the factory. Users only need deionized water for baseline calibration on site, which is simple and reliable.

2. Intelligent Algorithm Anti-Interference, Turbidity Is No Longer a Problem

• Automatic Turbidity Compensation: Built-in scattering correction model, which can decouple the additional attenuation caused by suspended particle scattering in real time, effectively reducing turbidity cross-interference, so that parameters such as COD and chromaticity maintain ±5%F.S. accuracy within 0~400NTU.

• Adapt to Dynamic Water Quality: When water turbidity fluctuates in a short time, no human intervention is required. The sensor can automatically adjust compensation coefficients to ensure the authenticity of data trends.

3. Engineered Design, Adapting to All-weather Online Monitoring

• IP68 Full Sealing Protection: 316L stainless steel shell, corrosion-resistant and salt spray resistant, suitable for long-term immersion environments such as river courses, municipal sewage, aquaculture and industrial discharge outlets.

• Low Power Consumption 0.2W@12V: Typical power consumption is only 0.2W, which can support solar-powered or battery-powered stations, significantly reducing system power distribution costs.

• RS485 Interface, Modbus/RTU Protocol: Standard industrial bus, maximum transmission distance up to 1200 meters, easy to mount on existing data collectors or RTUs. The protocol is open, with complete code examples, and development and debugging are efficient.

• Anti-vibration and Anti-water Flow Impact: Compact structure, no vulnerable rotating parts (self-cleaning brush is optional), cable connector adopts M16-5 core waterproof male head, wiring is firm and reliable.

4. True Maintenance-Free, Reducing TCO

• No reagents, no pump tubes, no risk of valve blockage.

• The optical window is recommended to be wiped regularly according to the degree of on-site contamination (not daily operation). After 18 months of continuous use, only factory maintenance of the dynamic sealing device is required (with self-cleaning brush version).

• Extremely low annual operation and maintenance labor and consumable costs, especially suitable for unattended stations.

NBL-WQ-FUV-200 Online Full-Spectrum Multi-Parameter Sensor Technical Specifications

Note: COD, TOC, BOD values are all calibrated based on standard substances. For specific water samples, it is recommended to perform correlation comparison.

Typical Application Scenarios

• Surface water and river section monitoring: Real-time monitoring of organic pollution trends (COD/TOC) and turbidity changes in rivers and lakes, supporting long-term operation without reagents.

• Municipal sewage plant process monitoring: Installed at aeration tank outlet or secondary sedimentation tank to quickly feedback COD and chromaticity removal effects and assist precise process regulation.

• Industrial wastewater discharge outlet monitoring: Responding to sudden discharges in chemical, printing and dyeing, pharmaceutical and other industries. Full-spectrum characteristics can help identify abnormal bands and warn of exceedance risks.

• Water source and drinking water safety early warning: Monitor organic matter, chromaticity and other indicators in raw water as the front-end sentinel of pretreatment processes.

• Aquaculture and ecological restoration: Low power consumption and maintenance-free characteristics are suitable for large-area deployment, tracking dissolved organic matter and turbidity to ensure aquaculture environment.

Wiring and Installation Points

Electrical Connection (4-core twisted pair shielded cable)

Precautions:

• Power must be disconnected before wiring, strictly check the wire sequence to avoid damage to the equipment due to wrong connection.

• All cable connections must be waterproofed (glue filling or waterproof junction box), especially in long-term immersion or outdoor environments.

• It is recommended to add protective sleeves to the sensor cable to avoid wear or tension.

Installation Requirements

• The sensor should be submerged at least 30cm below the lowest water level to avoid exposure to the surface.

• Fix horizontally, with the measurement window facing the water flow direction to ensure real-time water sample renewal.

• Avoid installation in areas with dense bubbles or dead water flow zones.

FAQ

Q1. Does the NBL-WQ-FUV-200 need to replace reagents regularly?

A: No. The sensor adopts pure optical full-spectrum method, does not require any chemical reagents, truly pollution-free and reagent-free maintenance.

Q2. Will a large amount of suspended solids in water affect the measurement?

A: The sensor has a built-in automatic turbidity compensation algorithm, which can significantly suppress the interference of high turbidity on parameters such as COD and chromaticity. However, in extremely high turbidity (>400NTU) or strong bubble environments, it is recommended to add pretreatment or adjust the installation position.

Q3. Can the sensor output data be directly connected to existing PLC or DTU?

A: Yes. The sensor adopts standard Modbus/RTU protocol and RS485 interface, and provides standard register address table, which can be quickly connected with mainstream PLCs such as Siemens, Mitsubishi, Delta and various DTUs.

Q4. Are parameters such as COD, BOD, and TOC directly measured?

A: The sensor establishes correlation models based on spectral absorption characteristics and standard substances (such as KHP for COD), and outputs equivalent values. For specific water samples, it is recommended to perform 10-20 sets of comparison corrections with laboratory standard methods to obtain better correlation.

Q5. Is the waterproof performance reliable when the sensor is immersed in water for a long time?

A: The whole machine reaches IP68 protection level (can be continuously immersed under 0.1MPa pressure, about 10 meters water depth), and the shell is 316L stainless steel. However, the cable connector needs to be sealed by the user, and a waterproof connector is provided.

Q6. Do I need to clean the sensor window frequently?

A: It depends on the degree of water pollution. In general surface water environments, it is recommended to check and clean once every 1-2 weeks. For sewage discharge outlets, it can be shortened to weekly or shorter. When cleaning, use a soft cloth dipped in clean water or mild detergent, and avoid scratching the optical window.

Q7. What is the sensor operating voltage range? Is the power consumption really low?

A: Supports 12-24VDC (±10%), typical power consumption is only 0.2W (about 17mA at 12V), which is very suitable for field solar or battery powered systems.

Q8. If I want to customize longer cables or special installation brackets, can NiuBoL provide them?

A: Yes. Standard supply is 5-meter cable, longer distances (such as 10 meters, 20 meters) can be customized when ordering. At the same time, NiuBoL provides stainless steel submersible installation brackets and float solutions. Please consult sales engineers for details.
