Frequently Asked Questions (FAQ)
Q What measurement principle does the Blue-Green Algae sensor use?
The LMS-BGA100 uses fluorescence-based detection. A specialized UV light source excites chlorophyll in blue-green algae (cyanobacteria), and the emitted fluorescence is measured to determine algal cell concentration. This method is highly selective and minimizes interference from suspended particles and water color.
Q What is the measurement range of the Blue-Green Algae sensor?
The sensor covers a measurement range of 0–2,000,000 cells/ml with an accuracy of ±3% F.S., making it suitable for both low-concentration monitoring in clean water bodies and high-concentration detection during algal bloom events.
Q Does the sensor require regular chemical reagents or calibration consumables?
No. The Blue-Green Algae sensor operates on a reagent-free principle. It requires no chemical consumables during normal operation, which significantly reduces running costs and eliminates the risk of secondary chemical pollution in the monitored water body.
Q How does the sensor handle turbidity interference in the water?
The sensor features an automatic turbidity compensation algorithm that dynamically corrects measurement readings based on real-time turbidity levels. This ensures accurate algae concentration data even in sediment-rich, murky, or variable-quality water environments.
Q What communication protocol does the sensor support, and how is it integrated into a monitoring system?
The sensor outputs data via RS-485 using the MODBUS protocol, which is widely supported by SCADA systems, data loggers, PLCs, and water quality monitoring platforms. It operates on a 9–24VDC power supply (12VDC recommended), making integration straightforward.
Q How is the sensor maintained, and is it suitable for long-term deployment?
The sensor is equipped with an integrated self-cleaning wiper system that automatically removes biofilm and fouling from the optical window. Combined with its 316L stainless steel housing, it is designed for continuous, long-term deployment in challenging aquatic environments with minimal manual maintenance.
