The assembly can be fitted and mounted depending on the ambient conditions. Please note thefollowing:• Standard version
The immersion tube has an outer diameter of 40 mm (1.6 in). It is used for fixed installation orwith a pendulum holder. (The pendulum holder is part of the CYH112 holder system)• With chain retainer
The immersion tube is suspended from a chain at the top by hooking it into a multifunctional
clamp ring and a stainless steel bracket. (The chain is part of the CYH112 holder system)• With float
The immersion tube (PVC) is fitted with a float. Combined with a pendulum holder, the float isused for varying water levels. (The pendulum holder is part of the CYH112 holder system)
The CYH112 holder system is particularly suitable for use with the assembly, and has been
specially designed for this assembly.

Available lengths From 600 mm (23.6 in), are delivered in pieces measuring 600 mm (23.6 in) and
1 200 mm (47.2 in)Maximum length 2 400 mm (94.5)

Immersion tubes measuring up to 1 200 mm (47.2 in), straight or with 45° connecting pipe, areready to install on delivery. Tubes longer than 1 200 mm (47.2 in) must be glued by the client onsite. The necessary materials (glue (depending on the version), cleaning cloths, adhesive fitting) are
included in the delivery.
In the case of the chain retainer, the PVC assemblies are fitted with stainless steel weights forstabilization purposes (prevent buoyancy).

‣ Use 1 weight for an immersion tube measuring 600 mm (23.6 in), use 2 weights for an
immersion tube measuring 1 200 mm (47.2 in).

Quick fastener (optional)
The quick fastener enables:• Quick and easy installation and replacement of Memosens sensors with an inductive plug-in
connection. When using sensors with a fixed cable connection, it is not necessary to untwist theconnecting cables.
• The alignment of the installed sensors
The quick fastener is installed between the sensor and the assembly.

Power supply
Potential equalization

Potential equalization must be implemented at the place of installation. All electrically conductive
parts must be interconnected.
For use in hazardous areas:• There must be an electrically conductive connection between the immersion tube side of theassembly and the holder/fastener.
• If the assembly is secured using a chain and retaining bracket, a separate conductor for potential
matching must be routed alongside the measuring cable.
• If sensors have accessible metal surfaces, these sensors must be included in the potential
equalization system as indicated in the Operating Instructions for the sensor in question.

Endress+Hauser

Flexdip CYA112

Installation• Select the mounting location so that a sufficient distance from fixed installations is maintained,
and the sensor cannot be damaged even when the medium is moving.
• For fixed installation, the retaining point must be selected in a way that guarantees the proper
operation and maintenance of the assembly.
• The immersion tube must protrude over the retaining point by at least 100 mm (3.94 in).

Installation instructions• Potential equalization must be implemented at the place of installation.
• All electrically conductive parts must be interconnected.

Certificates and approvals
Ex approval

The stainless steel version of the CYA112 assembly (CYA112-**21*2**) may also be used in thehazardous area in Zone 1 and 2.
It does not have special Ex identification labeling, as the assembly does not have a potential ignition
source of its own and ATEX Directive 2014/34/EU therefore does not apply.
If sensors have accessible metal surfaces, these sensors must be included in the potential
equalization system as indicated in the Operating Instructions for the sensor in question.
