The pressure inside a vacuum insulation panel (VIP) is an important indicator for thermal insulation properties. The sensor transponder described in this paper fulfils the function of contact less measurement of pressure and temperature through covering layers and presents the best opportunity of quality assurance. The sensor transponder is placed inside the VIP and consists of a fully integrated microelectronic circuit and an antenna, both mounted on a printed circuit board. Measurements are taken with a mobile reader unit.
