Thermocouples (data sheet 8636)

Intrinsically safe


The thermocouple models TTeSrXiA and TTeSrXiAT with fabricated thermowells form 2, 2G and 2F according to DIN 43 772 have an EU Type Examination Certificate for the ignition protection type “intrinsic safety”. Both models meet the requirements of the directive 2014/34/EU for the application in potentially explosive atmospheres due to gases and dusts. The thermocouples can be mounted directly into the process. The measuring insert can be replaced as separate component.
For both models, we offer various thermocouple materials according to DIN EN 60 584. In addition, model TTeSrXiAT is available with several fitted transmitters with analogue or digital output.
