TU8325 B&C Electronics Submersible Turbidity Sensor

He submersible turbidity sensor TU8325 from B&C Electronics this Designed for continuous measurement of low turbidity in drinking water, water treatment, and industrial processes. Measurement is performed using the nephelometric method in accordance with applicable standards. ISO 7027 and EN 27027, using infrared light and 90° scattered light detection.

Unlike in-line turbidity probes, the TU8325 It is specially designed for submerged applications in reservoirs, channels, tanks, measuring chambers or installations where direct measurement of the process liquid is required.

The probe incorporates a system of self-cleaning using compressed air, It consists of an integrated nozzle that directs a jet of air onto the sensor's optical area. This system helps reduce the accumulation of scale, solids, and organic deposits on the lenses, improving measurement stability in continuous monitoring applications.

The TU8325 allows you to select different turbidity scales up to 400 NTU, with a resolution of up to 0.001 NTU in the low range. Infrared measurement minimizes the influence of sample color, providing stable and repeatable readings in low turbidity applications.

The sensor has isolated analog output 4…20 mA and digital communication RS485 through protocols Modbus RTU and B&C ASCII, facilitating its integration into PLCs, SCADA systems, data loggers, and industrial monitoring systems.

In addition to turbidity measurement, the probe incorporates internal temperature compensation and self-diagnostic functions via an optical verification signal. This function allows monitoring of the lens condition and detection of issues such as fouling, dry cell, lack of contact with the sample, or excessive external light.

He TU8325 It is suitable for drinking water applications, ETAP, WWTP, industrial water treatment, filtration control, process tanks and continuous monitoring systems where a robust, submersible and self-cleaning probe is required.

For proper installation, the probe should ideally be submerged at an angle that facilitates the cleansing action of the rising air. The system requires clean air at a maximum pressure of 3 bar. The typical cleaning time is approximately 15 seconds, with an indicative frequency of two cycles per day, although these values depend on the application and the solids load of the process.

Thanks to her body in PVC, protection IP68, thread 2″ NPT With its industrial design for continuous operation, the TU8325 is a robust solution for submersible turbidity measurement in water installations and industrial processes.
