Thermocouples (data sheet 8635)

With flameproof enclosure

The thermocouple models TTeSrXdA and TTeSrXdAT with fabricated thermowells form 2, 2G and 2F according to DIN 43 772 have an EU Type Examination Certificate for the ignition protection type “flameproof enclosure”. 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 TTeSrXdAT is available with several fitted transmitters with analogue or digital output.
