Resistance thermometers – measuring insert (data sheet 8566)
The measuring inserts TPtMiXiAo and TPtMiXiAoT according to DIN 43 735 are solely intended for installation into protective fittings for electrical thermometers with connection heads form B according to DIN EN 50 446 and have an EU Type Examination Certificate for the ignition protection type “intrinsic safety”. Both models meet the requirements of the directive 2014/34/EU for the application in potentially explosive atmospheres due to gases and dusts.
For the operation in connection heads with flameproof enclosure (types XD-AD and XD-SD), the measuring inserts are optionally available with a sleeve, which forms, in combination with a socket, a flameproof gap in the connection head.
For both models, we offer various measuring resistors according to DIN EN 60 751. In addition, model TPtMiXiAoT is available with several fitted transmitters with analogue or digital output.
The measuring inserts shall only be used in a suitable housing.
