The assembly can be fitted and mounted depending on the ambient conditions. Please note the following:

• Standard version The immersion tube has an outer diameter of 40 mm (1.6 in). It is used for fixed installation or with 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 is used 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.

Stainless steel version

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 3 600 mm (141.7)

Thread M36 male thread

G1" female thread

Type of installation Primarily for fixed installation, the assembly can also be used with a chain retainer up to

1 200 mm (47.2 in)

The threaded joints are sealed with an O-ring.

Connecting pipes have a G1" thread for the sensors. Various sensor adapters are available (NPT ¾", G ¾", Pg 13.5) for sensors with other threads.

PVC version

Available lengths From 600 mm (23.6 in), are delivered in pieces measuring 600 mm (23.6 in) and

Immersion tubes measuring up to 1 200 mm (47.2 in), straight or with 45° connecting pipe, are ready to install on delivery. Tubes longer than 1 200 mm (47.2 in) must be glued by the client on site. 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 for stabilization purposes (prevent buoyancy).

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

Version with float

The assembly with a float is only available as a PVC version. The immersion depth of the sensors (depending on the sensor) is 600 mm (23.6 in). The assembly is preferably operated with the CYH112 pendulum holder. The installation is performed on site at the customer's premises. The float version does not contain any weights. This version is designed to compensate for varying water/ wastewater levels.

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 the connecting cables.

• The alignment of the installed sensors

The quick fastener is installed between the sensor and the assembly.

Power supply

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 the assembly 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.
