Uniclean 700 Series - Modular control system for automated sensor cleaning

In many measuring applications, pH sensors are exposed to contamination, corrosion, and abrasion. To ensure their functionality, the sensors need to be cleaned regularly. However, in many applications, a fully automated sensor maintenance system has not yet been economical.

Automatic sensor cleaning based on a modular principle

With the Uniclean 700 series, Knick is introducing a modular control system, that can be installed very quickly and cost-effectively as a flexible entry-level solution for automated sensor cleaning.
With its innovative concept and focused functionality, the Uniclean 700 complements the portfolio of the Uniclean 900 and Unical 9000 control units, which are used in Knick’s established cCare system for fully automated cleaning and calibration.

Modular configuration according to customer requirements

The modular configuration of the individual components allows a high degree of flexibility for the customer. However, the compact design makes installation very easy. With the Uniclean 700 control systems, Knick offers users a flexibly expandable solution that is suitable for use with static and retractable fittings. The fittings can be pneumatically or, in the near future, hydraulically driven.
The cost-effective solution is used in wastewater treatment plants and in metal processing, which are confronted with heavy soiling and high sensor wear. The Uniclean 700 series also excels in food production, where the sensors often become encrusted in sugar factories, for example.

Entry-level solution for pH sensors

With the Uniclean 700 series, Knick provides an entry-level system for the automatic cleaning of pH sensors, which is valuable in many industries. Unlike the Uniclean 900, the Uniclean 700 models do not require the special controlling program in the Protos transmitter. The cleaning process can be triggered by a simple switching signal, such as coming from the relay contact of a Stratos Multi and Protos II, or a simple pushbutton. The Uniclean 700 series also works with third-party transmitters or fittings.

The modular design allows for easy conversions when needed, so that the cleaning control systems can be quickly adapted to process changes.
Used components can be reused, and valves, for example, can be replaced quickly and easily. All necessary parts are available separately so that the final configuration of the Uniclean 710 and 720 can be carried out directly on site. The Uniclean 730 comes fully assembled and ready to use.

Uniclean 700 at the ACHEMA

Knick will be exhibiting the devices at this year’s ACHEMA in Frankfurt, Germany, the world’s leading trade fair for the chemical process industry. Every three years, about 77,000 visitors come here to learn about innovations in the industry. This year, ACHEMA opens its doors from June 10 to 14, and the Knick booth is located in Hall 11.1, Booth A45.
