Field of application

The Cleanfit CPA473 retractable assembly is designed for application in fibrous or sticky media. Its patented sleeve seals and integrated scrapers make sure that nothing sticks to the sensor. Cleanfit 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 CPA473 is intended for use in tanks and pipes in:

Chemical industry
Paper industry
Wastewater / industrial water
Power plants
Refuse incinerators

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
No process interruption for electrode cleaning and calibration – saves maintenance time and costs
Extended operating life of electrodes due to automatic cleaning
Suitable for application in sticky and fibrous media thanks to integrated scraper and sleeve seals
Flexible adaptation to all applications by great variety of materials and process connections
