Resistance thermometers (data sheet 8526)
The resistance thermometer models TPtHrXiA and TPtHrXiAT 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 “intrinsic safety” 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 TPtHrXiAT is available with several fitted transmitters with analogue or digital output.
