E+H Turbimax CUS52D Digital Turbidity Sensor
CUS52D-AA1AA2
The CUS52D Digital Turbidity Sensor delivers real-time, laboratory-grade accuracy for online drinking water quality monitoring and industrial process water treatment. Operating on the ISO 7027 90° scattered light principle, it features a hygienic, zero-product-loss inline design that installs directly into pipelines without requiring costly bypass lines. Equipped with smart Memosens digital technology, fast dynamic response (<1s), and liquid-free solid-state calibration standards, it significantly reduces maintenance costs and ensures long-term operational stability.
The CUS52D digital turbidity sensor is an advanced optical analytical probe specifically engineered for demanding drinking water and industrial process water applications. By strict compliance with the ISO 7027 standard utilizing near-infrared light at 860 nm, the sensor eliminates natural water color interferences to ensure unmatched long-term stability and continuous measurement precision across all water purification stages. Its intelligent sensor design allows direct inline installation into pressurized pipelines or specialized flow assemblies via standard hygienic process connections, eliminating the maintenance burdens, clogged sample lines, and continuous water waste associated with traditional bypass sampling systems.
Integrated with digital Memosens technology, the CUS52D revolutionizes routine operations by storing all calibration parameters, sensor history, and operating data directly within the smart sensor head. Field operators can perform precise multi-point lab calibrations in controlled environments prior to rapid plug-and-play field deployment. Coupled with inductive contact-free signal transmission, the system eliminates signal loss and moisture corrosion issues. Maintenance efficiency is further elevated by supporting liquid-free solid-state calibration references, eliminating operator exposure to hazardous, unstable Formazin liquid standards and providing a reliable, cost-effective solution for municipal water authorities and industrial plants worldwide.
FAQ
Q1: What are the main benefits of using ISO 7027 standard measurement for turbidity?
A: ISO 7027 mandates an 860 nm near-infrared light source and a 90° detection angle. This wavelength eliminates color interference in natural raw water (such as yellow humic acids), guaranteeing accurate turbidity reading regardless of water color variation.
Q2: How does the CUS52D prevent micro-bubbles from distorting turbidity measurements?
A: Micro-bubbles can cause artificial turbidity spikes. The CUS52D solves this through direct in-pipe installation under operating pressure (up to 10 bar), which forces bubbles to stay in solution. For atmospheric bypass flow cells, an optional specialized air bubble trap is available.
Q3: Is liquid Formazin required for field calibration?
A: No. Thanks to the optional solid-state calibration tool (CUY52), operators can perform routine sensor verification and zero/span adjustments safely without preparing hazardous, short-lived Formazin liquid solutions.
Q4: Can I integrate the CUS52D sensor into our existing PLC / SCADA platform?
A: Yes. The sensor communicates digitally via Memosens protocol. Paired with our multi-channel transmitters, it can easily output Modbus RTU, HART, Profibus DP, or 4-20mA signals into any standard PLC/SCADA control system.
