Thermocouples (data sheet 8625)
With flameproof enclosure
The thermocouple models TTeHrXdA and TTeHrXdAT are designed for the installation into solid drilled or fabricated thermometer thermowells (e.g. according to DIN 43 772). Without thermowell, this version must not be applied in pressurised media.
They have an EU Type Examination Certificate for the ignition protection type “flameproof enclosure” and meet the requirements of the directive 2014/34/EU for the application in potentially explosive atmospheres due to gases and dusts.
For both models, we offer various thermocouple materials according to DIN EN 60 584. In addition, model TTeHrXdAT is available with several fitted transmitters with analogue or digital output.
