Resistance thermometers (data sheet 8525)

With flameproof enclosure

The resistance thermometer models TPtHrXdA and TPtHrXdAT 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 measuring resistors according to DIN EN 60 751. In addition, model TPtHrXdAT is available with several fitted transmitters with analogue or digital output.
