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.

Introduction

The 80PK-27 SureGripTM Industrial Surface Temperature Probe is designed for reliably measuring temperatures to 600

°C (1112 °F) on flat or slightly convex surfaces, while retaining

a long service life.

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.
