  • Measuring insert for temperature measurement
    Patent number: 9074945
    Abstract: A temperature measuring insert composed of ceramic or sintered materials of magnesium oxide or aluminum oxide accomodates, on its end facing the measured medium, temperature sensor elements, such as thermocouples and temperature measuring resistors, as a measuring tip, installable singly or with others in metal or ceramic protective tubes. The site of the measuring tip, a water adsorption behavior differing from the remaining measuring insert material is present, in order to protect the temperature sensor elements in the case of rapid process related temperature changes, in order to prevent, in the case of heating, effects due to superheated steam.
