The tip of the Pt 100 temperature sensor (P/N 155 010 - not included in the
delivery) measures the gas temperature in the middle of the RUVAC’s dis-
charge flange (see Fig. 0.1 and 0.2. Depending on the size of the RUVAC
pump respectively its flange, the Pt 100 sensor needs to be fitted at different
positions. The temperature sensor Pt 100 is equipped with three installation
marks (
marks A,B,C , see Fig. 0.2). According to the information given in the
following table the Pt 100 must be inserted up to the respective mark into the
clamp fitting and secured reliably. In the enclosed installation instructions for
the clamp fitting, the required torque levels are stated. Before installing, the
transport protectors must be removed.
