XWWarning

To avoid electrical shock, do not use this probe
when voltages exceeding 24 V ac rms or 60 V dc
are present. The probe tip is electronically
connected to the output terminals.

XW Attention

Pour éviter les risques d’électrocution, ne pas
utiliser cette sonde quand la tension est
sepérieure à 24 V efficaces en courant alternatif
ou 60 V en courant continu. La pointe de la sonde
est reliée électriquement aux bornes de sorties.

XW Warnung

Um Elektroschock zu vermeiden, dürfen Sie den
Meßstift nicht in der Anwesenheit von
Spannungen über 24V Wechselstrom oder 60V
Gleichstrom verwenden. Die Spitze des Meßstifts
ist mit den Ausgangsanschlüssen elektrisch
verbunden.

XW Advertencia

Para evitar descargas eléctricas, no use esta
sonda cuando se apliquen voltajes que
sobrepasen 24 V ca rcm o 60 V cc. La punta de la
sonda está conectada eléctricamente a las
terminales de salida.

Measurement Considerations

Instrument Compatibility

The 80PK-27 is designed to be compatible with any
temperature measuring instrument that accepts Type K
thermocouples, has a miniature thermocouple connector, and
has cold reference junction compensation. Accuracy of the
temperature measuring instrument must be considered along
with the 80PK-27 accuracy specifications in order to determine
the overall accuracy of the combination.

Temperature Limitations

The probe tip has continuous temperature rating of 600 °C.

However the rest of the assembly is rated for a lower
temperature. See the specifications for further information.

Media Limitations

Media must be compatible with Chromel, Alumel, and 303
stainless steel.

Application Information

At high temperatures, a surface temperature probe removes a

small amount of heat from the measured surface. At 600 °C on

a polished metal surface, the temperature at a contact point

will be lowered, typically not more than 2 °C. A lowering of the

temperature at the contact point is less likely (and contact
response time is quicker) on clean, polished, thermally
conductive surfaces than on materials with low thermal
conductivity, such as plastic or rough, contaminated surfaces.
To obtain the best thermal contact and performance, the
stainless steel ring must make full and firm contact with the
measurement surface.
