4.1 Mounting requirements

For information on the conditions that must be present at the installation location in

order to ensure designated use (e.g. ambient temperature, degree of protection, climate

class etc.), and information on the device dimensions, see the 'Technical data' →  24

4.1.1 Orientation

No restrictions. However, self-draining in the process must be guaranteed. If there is an

opening to detect leaks at the process connection, this opening must be at the lowest possible

point.

4.1.2 Installation instructions

The immersion length of the compact thermometer can considerably influence the accuracy. If

the immersion length is too short, measurement errors can occur as a result of heat

conduction via the process connection and the vessel wall. If installing in a pipe, the

immersion length should ideally correspond to half of the pipe diameter.

Installation possibilities: pipes, tanks or other plant components.

The requirements of the EHEDG and the 3-A Sanitary Standard must be adhered to.

Installation instructions EHEDG/cleanability: Lt ≤ (Dt-dt)

Installation instructions 3-A/cleanability: Lt ≤ 2(Dt-dt)

In the case of pipes with a small nominal diameter, it is advisable for the tip of the

thermometer to project well into the process so that it extends past the pipe axis.

Installation at an angle (4) could be another solution. When determining the immersion

or insertion length, all the parameters of the thermometer and of the medium to be

measured must be taken into account (e.g. flow velocity, process pressure).

NOTICE

The following actions must be taken if a sealing ring (O-ring) or seal fails:

‣The thermometer must be removed.

‣The thread and the O-ring joint/sealing surface must be cleaned.

‣The sealing ring or seal must be replaced.

‣CIP must be performed after installation.

Easytemp TMR31, TMR35 Mounting

Endress+Hauser 11

In the case of weld-in connections, exercise the necessary degree of care when performing the

welding work on the process side:

1. Use suitable welding material.

2. Flush-weld or weld with welding radius ≥ 3.2 mm (0.13 in).

3. Avoid crevices, folds or gaps.

4. Ensure the surface is honed and mechanically polished, Ra ≤ 0.76 µm (30 µin).

Pay attention to the following when installing the thermometer to ensure that the cleanability

is not affected:

1. The thermometer is suitable to be cleaned in built-in condition for CIP (cleaning in

place). Cleaning is carried out in combination with tubing/piping or tank/vessel.

Thermometers installed in tanks/vessels in combination with dead legs: Ensure with the

installation of the cleaning instrument to spray directly the cleaning agent into the dead

leg for cleaning out.

2. The Varivent® couplings enable flush-mount installation.

4.2 Mounting the thermometer

Proceed as follows to mount the device:

1. The permitted loading capacity of the process connections can be found in the relevant

standards.

2. The process connection and compression fitting must comply with the maximum

specified process pressure.

3. Make sure that the device is installed and secured before applying the process pressure.

4. Adjust the loading capacity of the thermowell to the process conditions.

5. It may be necessary to calculate the static and dynamic loading capacity.

It is possible to verify the mechanical loading capacity as a function of the installation

and process conditions using the online TW Sizing Module for thermowells in the

Endress+Hauser Applicator software →  23.

4.2.1 Cylindrical threads

NOTICE

Seals must be used for cylindrical threads.

In the case of combined thermometer and thermowell assemblies, these seals are already

installed (depending on the version ordered).

‣The system operator is required to verify the suitability of this seal with regard to the

operating conditions.

1. Replace with a suitable seal if necessary.

2. Replace the seals following disassembly.

3. As all threads must be firmly tightened, using the appropriate torques.

4.2.2 Tapered threads

‣The operator must verify if additional sealing by means of PTFE tape, hemp or an

additional welded seam, for example, is necessary in the case of NPT threads or other

tapered threads.

4.3 Post-mounting check
