Function and system design
Functionality The process assembly CPA442 is used to install 12 mm sensors. You can install the assembly vertically
or angularly in pipes or reactors.
The assembly seals the sensor against the process. It is suitable for:
• CIP (cleaning in place)
• SIP (sterilization in place)
The stainless steel version and the Alloy C22 version are autoclavable.
Measuring system A complete measuring system comprises:
• Unifit CPA442 assembly
• 12 mm sensor, e.g. Orbisint CPS11D or Oxymax COS22D
• Transmitter, e.g. Liquiline CM44x
• Measuring cable

Reliability • The asssemblies are manufactured according to the certified quality criteria of Endress+Hauser.
• The assemblies are made of high-quality materials like stainless steel 1.4435 (AISI 316 L), Alloy C22
or highly resistant plastics like PVDF or PEEK. Only these materials and the respective sealings are
in contact with medium. The assemblies are manufactured from solid material (except the 15°
versions S and T).
• The assemblies are inline cleanable and inline sterilizable according to the EHEDG criteria.
• Certified versions and certificates are available.
