Beschreibung
Zusammenfassung:	To create a mobile unit, the temperature measuring apparatus and the pressure measuring apparatus are arranged on top of one another axially and accommodated in a cylindrical jacket. The pressure measuring apparatus can be formed by a resistance device which changes its resistance according to the pressure. The decoder devices for the measuring signals received from the temperature and pressure measuring apparatus can be formed by bridge connections. To record the measured quantities, a recorder, preferably a two-channel recorder, can be connected to the bridge collections.
