Field of application
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.
Cleanfit CPA474 is intended for use in tanks and pipes in:
It is suitable to be used with pressures of up to 10 bar (stainless steel cylinder) or 6 bar (PA cylinder).
Benefits
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
Success stories
Measurable and testable: Monitoring with Teqwave
