Encapsulated cable thermocouple

 

"PT" range

 


The simple construction of this multi-purpose temperature sensor makes it economical, easy and efficient to use. 

Operating temperatures are limited by the temperature resistance of the cable.

They may be contructed with one or two sensing elements depending on the applications : regulation, monitoring, data saving.....Different ways of setting up are possible: with fixed or adjustable fittings, compression spring to ensure contact with the measure taking area.  

Temperature range
-200°C to + 500°C depending on the components used

Mechanical data
The type of cable and the material used for the encapsulation are the key elements that define the sensor performances such as tensile strength, resistance to vibrations, resistance to the operating conditions.

Accuracy
Accuracy depends on :

  • the thermocouple wire tolerances as per IEC 751 standard. More information...
  • Reduced tolerances are possible on request


Applicable standards
IEC 60584
UTE 46201
Additionnal standards linked to specific applications are complied with upon customer request

Certification
Our "PT" range of thermocouples may be used in potentially explosive atmospheres provided that the requirements of the European Directive ATEX 94/9/CE and our EC-type examination certificate are complied with. More information ...
