Function and system design Operating principle The assembly is used as a stationary holder for installing 12mm sensors. It can be installed either vertically or at an angle in pipes or reactors. The assembly protects the sensor and seals it off from the process. It is suitable for:
- CIP (cleaning in place)
- SIP (sterilization in place) The versions in stainless steel 1.4435 (AISI 316 L) and Alloy C22 are autoclavable. Measuring system A complete measuring system comprises:
- Unifit CPA842 assembly
- 12 mm sensor (with shaft length 120 mm), e.g. pH Memosens CPS61E, conductivity Memosens CLS82E or oxygen COS81E
- Transmitter, e.g. Liquiline CM44x
- Measuring cable, e.g. CYK10 3 1 A B A0034675 1 Measuring system (example)

5 Sensor CPS61E
Dependability • The assemblies are manufactured in accordance with Endress+Hauser's certified quality criteria.
- The fixed assembly is manufactured from high-grade materials:
- Stainless steel 1.4435 as per BN2 (AISI 316 L)
- Only these materials and the relevant seal are in contact with the process medium.
- The assembly can be cleaned and sterilized inline in accordance with EHEDG criteria.
- Certified versions and certificates are available, depending on the version.

‣ The assembly is designed for installation on vessels and pipes. Suitable process connections must be available at the customer site for this purpose. ‣ The mounting seal, which seals the adapter from the process nozzle, must be provided by the customer (except in the versions DN25 standard and DN25 B. Braun port). ‣ Install the assembly only if the vessel is empty and the process is unpressurized. The assembly can be mounted at any angle from 0° to 360°. The installation conditions of the sensor used must be complied with. Example: 15° 15° A B 10° 10° C A0034731 2 Permitted angle of installation depending on sensor A Glass pH sensor: Installation angle at least 15° from the horizontal B ISFET pH sensor, conductivity sensor, oxygen sensor (optical): No restrictions, recommended 0 to 180°, where buildup can occur. C Oxygen sensor (amperometric): Installation angle at least 10° from the horizontal Only operate the CLS82E conductivity sensor with an assembly without sensor protection, to avoid influencing the measuring signal. COS81E-***U* oxygen sensor (u-shaped spot cap) Installation angle is limited to 0° to 180°
