This means that unknown and therefore unwanted heat loss flows through the surrounding atmosphere can be avoided, which can improve the measurement accuracy and therefore the significance of a measurement. In order to achieve a sufficiently high vacuum quality, it is important to use materials that are suitable for vacuum. For example, Pt100 temperature sensors with PTFE-insulated leads are used for temperature measurement. The signal and power cables have a vacuum-compatible Kapton® sheath. To increase the temperature measurement accuracy, a heat-conducting paste specially designed for vacuum applications is used. In addition to signal and power feed-throughs, the vacuum chamber has special feed-throughs for operating fluid-based heat exchangers.
