1. An apparatus for determining and/or monitoring a process variable of a medium in a containment, the apparatus comprising:
a temperature sensor configured to register a temperature, which temperature sensor is adapted to be securable to an outer surface of a wall of the containment;
at least one connection line configured to electrically contact the temperature sensor;
a securement device configured to secure both the temperature sensor and a near section of the at least one connection line at and near the temperature sensor and extending from the temperature sensor, to the outer surface of the wall of the containment; and
a heat conductive coupling unit configured to be arranged on the outer surface of the wall of the containment, such that the heat conductive coupling unit surrounds and is positioned externally of each of the temperature sensor, the near section of the at least one connection line, and the containment,
wherein at least the near section of the at least one connection line, the temperature sensor, and the heat conductive coupling unit are securable via the securement device to the outer surface of the wall, such that the near section extends along the wall and, together with the temperature sensor, is in thermal contact in a contact area with the outer surface of the wall of the containment, and the heat conductive coupling unit is positioned under the securement device and in thermal contact with the containment.
