2. Design and function
2.1 Description
The magnetic thermocouple assembly is designed as a non-welded option for vessel wall
temperature measurement.The circular magnet design incorporates an insulation barrier
from radiant heat along with a sensor tip designed to maximise surface contact to ensure
accurate temperature measurement.
The neck tube can be manufactured to length based on insulation thickness.The spring-
loaded neck tube ensures sensor contact with the vessel wall and allows for maintenance
without the use of tools above the insulation/cladding of the vessel.
This document describes instruments in standard version. For applications in hazardous
areas special instrument versions are required.

4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during internal
transport, proceed carefully and observe the symbols on the packaging.
▶
With internal transport, observe the instructions in chapter 4.2 “Packaging
and storage”.
If the instrument is transported from a cold into a warm environment, the formation of
condensation may result in instrument malfunction. Before putting it back into operation,
wait for the instrument temperature and the room temperature to equalise.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: 0 ... 70 °C [32 ... 158 °F]
■
Humidity: 35 ... 85 % relative humidity (no condensation)
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Hazardous environments, flammable atmospheres
Store the instrument in its original packaging in a location that fulfils the conditions listed
above. If the original packaging is not available, pack and store the instrument as described
below:
1. Place the instrument together with shock absorbing material in the packaging.
2. If stored for a prolonged period of time (more than 30 days), place a bag containing a
desiccant inside the packaging.
4. Transport, packaging and storage

5. Commissioning, operation
Only use original parts.
WARNING!
Physical injuries and damage to property and the environment caused
by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable
or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,
radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature
and under high pressure or vacuum may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
▶
Wear the requisite protective equipment (see chapter 3.6 “Personal
protective equipment”).
5.1 Mechanical mounting
Ensure there is enough MI cable or flex armour to reach the termination location for each
magnet thermocouple sensor.
■
Avoid passing thermocouple wire or flex armour through hot zones.
■
Ensure all surfaces attachment areas are cleaned by appropriate methods.
■
When grinding always use clean abrasive grinding materials that have not been used on
other materials.
■
Wire brushes or wheels are not appropriate tools for cleaning the surface.
■
Test fit the magnet thermocouple sensor at the desired location to ensure adequate
length of MI cable or flex armour was provided.
■
Ensure all bendings are correct and sufficient allowance is provided for movement.

5.1.2 Removal of insulation
WARNING!
Risk of penetrating the vessel surface
The centring pilot drill must be removed to avoid drilling through the vessel
wall.Vessel wall damage can compromise the integrity and wall thickness of
the vessel.
▶
Ensure proper speed and feed of drilling with removal of insulation to
measure depth of cut as required.
▶
Remove pilot drill as described below.

13WIKA operating instructions model TC52-M
14502900.01 12/2021 EN/DE/FR/ES

5.1.3 Vessel surface cleaning
Using a hand drill with auxillary side handle attachment begin cleaning the surface using a
50 mm [2 in] coarse grit sanding pad or coarse grit flap disc.
Surface must have scale and rust removed to provide proper adhesion of magnet. A bright
finish of the surface metal is preferred.
WARNING!
Risk of over grinding the vessel wall thickness
Vessel wall thickness is critical to proper operations. Over griding can cause
a weakened or thin section of the vessel wall.
▶
Use proper grinding methods and tools.
▶
Only remove scale and rust.
▶
Do not penetrate the vessel surface!

5.2 Electrical mounting
■
Only connect cables and lines in an unpowered state!
■
Fine-stranded leads must be finished with end splices.
■
Cables used must comply with the respective requirements in terms of stability and
temperature, strain and mobility. Over-working the cable may cause fraying of the wire.
■
Connection cables must be run so that any mechanical damage is prevented. This
includes areas where wear may occur resulting in fraying of the wire.
■
When bending connection cables it cannot be bent within 25 mm [1 in] of the transition
region.
■
Connection cables are not to be in contact with hot surfaces (i. e. hot manifolds).Where
this cannot be achieved proper selection of electrical wire, transition or high-temperature
sleeve shall be used.
