3. Specifications / 4. Design and function / 5. Transport, packaging, storage
It has been possible to reduce the short-range order effect in Type N (NiCrSi-NiSi)
thermocouples by alloying both legs with silicon. The effect is reversible and can be cancelled by
annealing above 700 °C with subsequent slow cooling. Thermocouples with smaler diameters
react sensitively in this respect. Even cooling in still air can cause deviations greater than 1 K.
GB
The application range of these thermometers is limited by the permissible max. temperature of the
thermocouple as well as the max. temperature of the thermowell material.
Listed thermocouples are available both as single or duplex thermocouples. The thermocouple
will be delivered with an insulated measuring point, unless explicitly specified otherwise.
Sensor tolerance value
A cold junction temperature of 0 °C is taken as basis with the definition of the sensor limiting
error of thermocouples. When using a compensating cable or thermocouple cable, an additional
measuring error must be considered.
For tolerance values and further specifications see current WIKA Data Sheet or order
documentation.

4. Design and function

4.1 Short description

These thermometers (resistance thermometers and thermocouples) detect temperatures in
processes. These thermometers are suitable for low, medium and high process requirements, in
hazardous areas.
They are assembled as thermometers with a connection head. Optionally, a transmitter can
be built into the connection head. For this transmitter, additional operating instructions will be
enclosed.
The thermometer can be combined with a large number of thermowell designs. Operation without
a thermowell is only appropriate in special cases.

4.2 Scope of delivery

Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage

5.1 Transport
Check instrument for any damage that may have been caused by transport. Obvious damage
must be reported immediately.
5.2 Packaging
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).
