FAQs
What is the measurement principle and detection limit of ADU3500?
ADU3500 adopts 90° laser scattering technology (660nm laser light source). It features an ultra-low detection limit of 0.005 NTU with an accuracy of 2% or ±0.02 NTU, enabling high-precision detection of trace suspended solids, microorganisms, and corrosion products in cooling liquids.
Can this turbidity sensor handle high pressure in liquid cooling loops?
Yes. The sensor is specifically designed with a pressurized flow cell structure capable of operating under pressure up to 0.6 MPa (and customizable up to 1.0 MPa). It allows real-time, online liquid monitoring directly within closed CDU pipelines without needing pressure reduction.
How does the automatic optical window cleaning function work?
The sensor features an integrated self-cleaning optical window mechanism that prevents particulate buildup and biological fouling. This maintains optical clarity over long continuous operation periods, greatly reducing manual maintenance frequency and system downtime.
What communication protocols and signal outputs are supported?
It supports digital RS485 output using standard Modbus-RTU communication protocol. In addition, a 4-20mA analog transmission output is optionally available for direct connection to PLCs, RTUs, and data center dynamic monitoring systems.
