Abstract
The present disclosure relates to an apparatus for determining and/or monitoring a process variable of a medium, comprising at least one sensor element arranged in a sensor head for determining and/or monitoring the process variable, wherein an internal volume of the sensor head is filled at least partially with a filler. The filler includes at least one fill material, for which at at least one predeterminable phase transformation temperature a phase change occurs, in which the material remains in the solid state, wherein the fill material is in a first phase state when a temperature of the fill material is less than the phase transformation temperature, and wherein the fill material is in a second phase state when the temperature of the fill material is greater than the phase transformation temperature.
