3.2.2 Potential measurement uncertainties
Important factors which counteract the long-term stability of thermocouples.
Ageing eects/poisoning
■
Oxidation processes in thermocouples which are not appropriately protected (“bare”
thermocouple wires) result in falsications of the characteristic curves.
■
Foreign atoms (poisoning) that diuse into the original alloys lead to changes of these original
alloys and thus falsify the characteristic curve.
■
The inuence of hydrogen leads to the embrittlement of the thermocouples.
The Ni leg of the type K thermocouple is often damaged by sulphur which is contained in exhaust
gases, for example. Thermocouple types J and T age slightly, as the pure metal leg oxidises rst.
In general, rising temperatures cause accelerated ageing eects.
Green rot
If type K thermocouples are used at temperatures from approx. 800 °C to 1,050 °C, considerable
changes of the thermoelectric voltage can occur. The cause of this is a chromium depletion or
the chrome oxidation in the NiCr leg (+ leg). The precondition for this is a low concentration of
oxygen or steam in the immediate environment of the thermocouple. The nickel leg is not aected
by it. The consequence of this eect is a drift of the measured value caused by decreasing
thermoelectric voltage. This eect is accelerated if there is a shortage of oxygen (reducing
atmosphere), since a complete oxide layer, which would protect it from further oxidation of the
chromium, cannot be formed on the surface of the thermocouple.
Recommended max. operating temperature
GB
The thermocouple is permanently destroyed by this process. The name green rot is derived from
the greenish shimmering colouration on the breaking point of the wire.
The thermocouple type N has in this regard an advantage due to its silicium content. Here, a
protective oxide layer forms on its surface under the same conditions.
K eect
The NiCr leg of a type K thermocouple has an ordered alignment with respect to the alignment
in the crystal lattice below approx. 400 °C. If the thermocouple is heated further, a transition to
a disordered state occurs in the temperature range between approx. 400 °C and 600 °C. Above
600 °C, an ordered crystal lattice is restored.
11208287.06 10/2013 GB/D/F/E
WIKA operating instructions resistance thermometers, thermocouples

3. Specications / 4. Design and function
If these thermocouples cool too quickly (quicker than approx. 100 °C per hour), the undesirable
disordered crystal lattice occurs again during cooling in the range from approx. 600 °C to
approx. 400 °C. In the characteristic curve of type K, however, a consistently ordered alignment
state is assumed and provided with values. This results in a fault of thermoelectric voltage of up
GB
to approx. 0.8 mV (approx. 5 °C) in this range. The K eect is reversible and is largely eliminated
again by annealing above 700 °C, followed by correspondingly slow cooling.
Thin sheathed thermocouples are particularly sensitive in this respect. Cooling in resting air can
already lead to deviations of 1 K.
In type N thermocouple, it has been possible to reduce this short-range-order eect by alloying
both legs with silicium.
The application range of these thermometers is limited both by the permissible maximum
temperature of the thermocouple and by the max. temperature of the thermowell material.
Listed models are available both as single or dual thermocouples. The thermocouple will be
delivered with an insulated measuring point, unless explicitly specied otherwise.
Tolerance value
For the tolerance value of thermocouples, a cold junction temperature of 0 °C has been taken as
the basis. When using a compensating cable or thermocouple cable, an additional measuring
error must be considered.
For limiting deviations and further specications, see the corresponding WIKA data sheet and
technical information sheet IN 00.23, “Application of thermocouples”.
4. Design and function
4.1 Description
These thermometers (resistance thermometers and thermocouples) detect temperatures in
processes. These thermometers are suitable, depending on the version, for low, medium and high
process requirements.
They can be assembled as cable probes or as thermometers with a connection head. Optionally,
a temperature transmitter can be built into the connection head. For this temperature transmitter,
separate operating instructions will be enclosed.
Certain thermometer versions can be combined with a large number of thermowell designs.
Operation of these thermometers without a thermowell is only appropriate in special cases.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.

6.2 Cable connections
The cable gland must be optimally sealed, to ensure that the required protection class is reached.
Requirements for meeting ingress protection
■
Only use cable glands within their indicated clamping range (cable diameter suitable for the
cable gland)
■
Do not use the lower clamping area with very soft cable types
■
Only use circular cross-section cables (if necessary, slightly oval in cross-section)
■
Do not twist the cable
■
Repeated opening/closing is possible; however only if necessary, as it might have a detrimental
eect on the protection class
■
For cable with a pronounced cold-ow behaviour the screw connection must be fully tightened
CAUTION!
■
The protection class is not valid with armoured cables (stainless steel sheathed)
■
Seal should be checked for signs of brittleness and, if necessary, replaced
6.3 Parallel threads
If the thermometer connecting head, extension neck, thermowell or process connection are
connected to parallel threads (e.g. G ½, M20 x 1.5 ...), these threads must be secured using seals
which prevent liquids from penetrating into the thermometer.
As standard, WIKA uses copper prole seals for the connection between the neck tube and the
thermowell, and at paper seals for the connection of the connection head and the extension neck
or thermowell.
If the thermometer and the thermowell are already connected, the seals will already be mounted.
The plant operator must check whether the seals are suitable for the operating conditions and
must replace them, if necessary, with suitable seals.
For thermometers without a thermowell, and/or where these are delivered separately, the seals
are not included and must be ordered separately.
GB
Tighten the threads by hand when carrying out the nal assembly on the plant. This will
correspond to the delivery status of the premounted components. The nal tightening torque
should be applied using a spanner (half rotation).
The seals must be replaced after dismantling!
The seals can be ordered from WIKA, indicating the WIKA order number and/or the
designation (see table).
