3 Installation
Please check by referring to the technical data whether or not your gauge is
suitable for your application.
The Penning Gauge PEG100 should preferably be mounted flange down. Inclined
installation is possible but the horizontal orientation must not be exceeded.
Flange up installation is not permissible because under such circumstances con-
densate may collect in the PEG100. This will either adversely affect the measure-
ments, or the sensor itself may possibly be damaged.
The Penning Gauge is equipped with a DN 25 KF or a DN 40 CF connection
flange. The DN 25 KF flange is used to connect the gauge to the mating connec-
tion flange on a vacuum system with the aid of a centering ring and a clamping
ring.
The cathode plate (7/5) also acts as a baffle.
The supply voltage and the high voltage switching signal as well as the measure-
ment voltage signal are carried through the 8-way FCC 68 socket.
