Thermocouple with process display (data sheet 8690)

With flameproof enclosure, intrinsically safe

The thermocouple model TTePAXd is 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.
TTePAXd is equipped with a rugged die-cast aluminum case with an integrated backlit LC-graphic display, which communicates digitally with the fitted transmitter type 5337-D via HART interface. Both digital display and transmitter can be parameterised via optical keyboard through the window of the instrument without having to remove the screw-on lid.
TTePAXd has an EU Type Examination Certificate for the ignition protection types “flameproof enclosure” and “intrinsic safety” and meets the requirements of the directive 2014/34/EU for the application in potentially explosive atmospheres due to gases and dusts.
