RS485 Modbus RTU Suspended Solids Sensor Submersible Tss Transmitter

The stainless steel model uses light absorption for 0 to 20000 mg/L ranges, while the plastic model uses light scattering for 0 to 5000 mg/L, matching principle to concentration level.

Built-in self-cleaning mechanism on the stainless steel variant actively removes air bubbles, biological slime, and sludge particles from the optical window.

Optical measurement uses modulated light and electronic filtering to block sunlight and facility lighting from influencing readings, enabling reliable outdoor and open-tank deployments.

Integrated temperature sensor automatically compensates for optical interference caused by color changes in high-concentration suspended solids water, improving accuracy.

Stainless steel model covers 0 to 200, 0 to 1000, 0 to 5000, and 0 to 20000 mg/L ranges at 0.1 mg/L resolution, spanning clean natural water to heavily loaded industrial wastewater.

The stainless steel variant's self-cleaning module is rated for 18 months of service, keeping consumable replacement intervals long and maintenance costs low in continuous monitoring applications.

Full IP68 waterproof protection combined with an external anti-interference shielded cable ensures stable signal output even in electrically noisy industrial and wastewater treatment environments.

Installation guidelines specify horizontal mounting to reduce the chance of foreign matter settling directly on the optical measurement surface.

On-site slope adjustment using actual application sludge corrects for differences in light absorption characteristics between sludge types and compositions.

Standardized NPT 3/4 threading supports both fixed pipe installation and connection to Renke portable analyzer for mobile field spot-checks without additional adapters or fittings.
