Technical Information

iTHERM TT411

Welded thermowell

Use in hygienic and aseptic applications in the food & beverages and pharmaceutical industries

Applications

• Specially designed for use in hygienic and aseptic applications in the Food & Beverages and Life Sciences industries

• Pressure range up to 40 bar (580 psi)

• For increased protection requirements of the temperature sensor regarding physical and chemical effects

Installation instructions

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.

The immersion length of the thermometer can influence the accuracy. If the immersion length is too small then errors in the measurement are caused by heat conduction via the process connection and the container wall. If installing into a pipe then the immersion length should ideally be half of the pipe diameter.

Installation possibilities: Pipes, tanks or other plant components

 1 Installation examples

1, 2 Perpendicular to flow direction, installed at a min. angle of 3° to ensure self-draining 3 On elbows 4 Inclined installation in pipes with a small nominal diameter U Immersion length

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 length or installation depth all the parameters of the thermometer and of the medium to be measured must be taken into account (e.g. flow velocity, process pressure).

For immersion lengths U < 70 mm (27.5 in), the use of iTHERM QuickSens inserts is recommended..

The counterpieces for the process connections and the seals or sealing rings are not included in the scope of supply for the thermometer. Liquiphant M weld-in adapters with associated seal kits are available as accessories. .

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

• Remove the thermometer, clean the thread and the O-ring joint/sealing surface

• Replace the sealing ring or seal

• Perform CIP after installation In the case of weld-in connections, exercise the necessary degree of care when performing the

welding work on the process side:

• Suitable welding material

• Flush-welded or with welding radius >= 3.2 mm (0.13 in)

• No recesses, folds or gaps

• Honed and polished surface, Ra ≤ 0.76 µm (30 µin)

Thermal shock resistance in CIP/SIP process with a temperature increase and decrease from +5 to +130 °C (+41 to +266 °F) within 2 seconds.

The maximum possible process pressure depends on various influencing factors, such as the design, process connection and process temperature. For information on the maximum possible process pressures for the individual process connections, see the 'Process connection' section. →  13

It is possible to check the mechanical loading capacity as a function of the installation and process conditions online in the TW Sizing Module for protection tubes in the Endress+Hauser Applicator software. This is valid for DIN thermowell calculations. See 'Accessories' section.

Example of the permitted flow velocity depending on the immersion length and process medium

The highest flow velocity tolerated by the protection tube diminishes with increasing insert immersion length exposed to the stream of the fluid. In addition, it is dependent on the diameter of the tip of the protection tube, the medium type, process temperature and process pressure. The following figures exemplify the maximum permitted flow velocities in water and superheated steam at a process pressure of 40 bar (580 PSI).

All dimensions in mm (in). The design depends on the thermowell version:

• Diameter 6 mm (¹⁄₄ in)

• Diameter 9 mm (0.35 in)

• Diameter 12.7 mm (¹⁄₂ in)

• T-piece and elbow piece thermowell version as per DIN 11865 / ASME BPE for weld-in

Various dimensions, such as the immersion length U for example, are variable values and are therefore indicated as items in the following dimensional drawings.
