Waterproof UV Sensor for Water Disinfection – UV-Water-PTFE
UV-Water-PTFE – Waterproof UV Sensor for Precise Lamp Monitoring in Water Disinfection and Sterilisation Systems
The UV-Water-PTFE from SGLUX GmbH is a high-precision waterproof UV sensor designed for water disinfection and sterilisation applications.
It combines a solar-blind Silicon Carbide (SiC) photodiode with a PTFE-sealed housing, ensuring long-term operation in chemically aggressive or saline water.
Engineered for the germicidal UV-C range (230 – 280 nm), it continuously measures the radiant intensity of low-pressure mercury or UV-LED lamps.
The PTFE body provides exceptional chemical resistance, while the UV-grade quartz window ensures high optical transmission and protection against fouling.
Factory-calibrated and traceable to NIST / PTB standards, the UV-Water-PTFE guarantees accuracy, repeatability, and regulatory compliance in drinking-water, wastewater, and process-water disinfection systems.
Compact, rugged, and maintenance-free, it is ideal for UV reactor validation, lamp output control, and real-time disinfection performance assurance.
Understanding Waterproof UV Sensor for Water Disinfection - UV-Water-PTFE
The UV-Water-PTFE detects germicidal UV radiation (254 nm) directly inside disinfection chambers or pipelines.
Its solar-blind SiC photodiode produces a proportional electrical output representing UV intensity, enabling automatic system control and validation.
The PTFE enclosure resists chemical attack from chlorinated or saline water, extending operational life where stainless-steel sensors are unsuitable.
With IP68 sealing, temperature stability, and traceable calibration, the UV-Water-PTFE ensures reliable lamp monitoring for both mercury-lamp and UV-LED water disinfection systems.
It is a critical component for achieving consistent microbial inactivation and regulatory compliance in modern UV sterilisation plants.
