The Endress+Hauser CAS51D-AAC2A4 is a digital UV photometric sensor from the Viomax CAS51D series. It measures Spectral Absorption Coefficient (SAC) and nitrate concentration in water and wastewater applications. Utilizing Memosens digital technology, it features a 15-meter fixed cable for direct connection to Liquiline transmitters, ensuring data integrity and simplified maintenance.
Dual-Parameter UV Sensing: Provides reliable measurement of SAC (UV254) as a surrogate for COD/BOD/TOC and direct nitrate concentration, ideal for biological treatment monitoring.
Memosens Digital Protocol: Contactless inductive connection prevents corrosion; stores calibration data and sensor diagnostics directly in the sensor head.
Robust Deployment Ready: The 15-meter fixed cable eliminates the need for separate sensor cables, reducing installation points of failure in open-channel or tank applications.
Low Maintenance Design: 316L stainless steel construction resists fouling and chemical attack in harsh wastewater environments.
Applications
Wastewater Treatment: Monitoring of denitrification processes, effluent quality, and load measurement at inlet/outlet.
Drinking Water: Surveillance of raw water quality and nitrate levels in municipal supplies.
Surface Water: Environmental monitoring of rivers and lakes for organic pollution indicators.
