Endress Hauser Process assembly CPA640 CPA482
The Ecofit CPA640 and Cleanfit CPA482 are process assemblies from Endress+Hauser, designed for the fixed installation of 120 mm pH/ORP and dissolved oxygen sensors in pipes and vessels. Each model is engineered for distinct application profiles, with the CPA640 optimized for cost-sensitive water and wastewater measurement, and the CPA482 built for demanding chemical and industrial processes.
Key Features and Benefits
-
Application-Specific Design: The CPA640 is the universal, cost-efficient solution for water treatment, wastewater treatment, condensate treatment, and cooling water circuits, suitable for pressures up to 10 bar. The CPA482 is designed for demanding process applications, handling pressures up to 14 bar and temperatures up to 140 °C.
-
Universal Sensor Compatibility: The CPA640 accommodates all standard 120 mm sensors with Pg 13.5 connection, including both analog and Memosens sensors. The CPA482 similarly supports 120 mm sensors for process measurement.
-
Quick Installation and Removal: Threaded connections enable fast installation and removal of the assembly, minimizing downtime during maintenance.
-
Flexible Material Options: The CPA640 adapter body is available in PVDF, stainless steel 316L (1.4404/1.4435), or Monel, with seal rings in Viton, EPDM, Chemraz, or Kalrez to suit diverse media. The CPA482 features wetted parts in stainless steel 1.4404 with EPDM or Viton O-rings.
-
Cost-Efficient Design: The CPA640 is specifically engineered to reduce the total cost of ownership for standard pH measuring points, allowing reuse of the threaded adapter and wiring cable when replacing sensors.

Endress Hauser Process assembly CPA640 CPA482
The Ecofit CPA640 and Cleanfit CPA482 are process assemblies from Endress+Hauser, designed for the fixed installation of 120 mm pH/ORP and dissolved oxygen sensors in pipes and vessels.
The Ecofit CPA640 is a universal process assembly specifically engineered for cost-sensitive water and process applications. It provides fixed installation for any standard 120 mm sensor with Pg 13.5 connection, including both analog and Memosens sensors. The assembly is intended for installation in pipes across wastewater treatment, water treatment, condensate treatment, and cooling water circuits, and is suitable for pressures up to 10 bar. Its threaded connections enable quick installation and removal, while various seal materials—including Viton, EPDM, Chemraz, and Kalrez—allow adaptation to diverse process conditions. The adapter body is available in PVDF, stainless steel 316L (1.4404/1.4435), or Monel, with process connections including NPT ½”, NPT ¾”, NPT 1″, and M25 x 1.5. The CPA640 is designed as a cost-efficient solution that reduces the total cost of ownership for standard pH measuring points by allowing reuse of the threaded adapter and wiring cable when sensors are replaced.
The Cleanfit CPA482 is a process assembly designed for more demanding industrial applications, handling higher pressures and temperatures than the CPA640. It accommodates 120 mm sensors and operates at pressures up to 14 bar and temperatures up to 140 °C. Wetted parts are constructed of stainless steel 1.4404, with O-rings available in EPDM or Viton for reliable sealing in aggressive media. This makes the CPA482 suitable for chemical, petrochemical, and other industrial processes where higher performance specifications are required.
