Resistance thermometer with process display (data sheet 8590)
With flameproof enclosure, intrinsically safe
The resistance thermometer model TPtPAXd 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.
TPtPAXd 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.
TPtPAXd 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.
