Manual or automatic retractable assembly Cleanfit CPA474
Brand: Endress+Hauser Group Services AG
The Cleanfit CPA474 retractable assembly is designed for applications which require safe separation from the process and contain media that could affect stainless steel. It offers highest operating comfort: You can replace sensors and even service the assembly while the process is running. The optional electric or pneumatic control system enables automated cleaning and calibration even in difficult processes.Features
- Safe and reliable separation from the process by ball valve, even under harsh conditions
- Suitable for corrosive media: Only polymers (PP, PVDF, PEEK) in contact with medium
- No process interruption for electrode cleaning and calibration – saves maintenance time and costs
- Extended operating life of electrodes due to automatic cleaning
- Flexible adaptation to all applications by great variety of materials and process connections
