Principle Overview

Because the rotor of a valve is typically not in contact with the housing, continuous monitoring of the electrical signals between the rotor and housing indicates scratching when the rated value changes and a system alarm signal is generated through circuit conversion of the electrical signal.

Rotor Interference Detection 

• High Processing Precision: Doebritz valves are well-designed to typically avoid scratching between on the rotor and the valve housing.
• High-strength structure. The valve features a high-tension design that enhances its stability. Foreign object impact The rotor may be scraped by foreign objects inside the valve
•  Doebritz System: It is recommended to install a rotor scratch detection RID-system to monitor scratch conditions.
•  Alarm mechanism: The Doebritz system issues an alarm when scratching occurs, prompting a shutdown to reduce the risk of damage.
