Mooring resistance thermometers are preferably used for temperature measurements in closed pipe systems & other rounded or flat surfaces The indirect temperature prevents interference of the medium in terms of flow On The other h&, pressure & chemical effects have no impact on the life of the resistance thermometer. The target is hardly influenced by the low thermal mass. The measuring insert is fitted with a Pt 100 temperature sensor as per EN 60 751, Class B in two-wire circuit.
