Hach Sonatax sc with sc200 Profibus controller

The Hach Sonatax sc with sc200 controller allows users to optimise sludge extraction, manage recirculation and be warned of potential solids washouts or process upset by continuously measuring the sludge blanket level. Its digitised probe eliminates electromagnetic interferences and features a quick LED system check. For a graphical display of sludge profile, the Sonatax sc probe must be connected to an sc1000 controller.

The unit’s wiper design is claimed to reduce maintenance and the probe features automatic frequency adjustment which scans a range of frequencies to find the ideal settings for the solids concentration for the application. Built-in software disregards signals reflected from tank structures such as pipes, rods, etc.

The digitised probe instantly resumes measurements after skimmer passes and the built-in position sensor also compensates for angle when the probe is not mounted exactly vertically.

Featuring automatic temperature compensation to ensure ultrasonic measurement is unaffected by seasonal changes in water temperature, seasonal calibration becomes unnecessary.

Troubleshooting, particularly in applications with multiple sludge blanket level probes connected to one controller, is quick and easy.
