- Remove the protective cover (is required again during maintenance work!)
- Make vacuum connection via small flange DN25 ISO KF (VSM77), DN40 ISO
KF (VSM78) or conflat flange DN40CF (VSM79)
- Use clamps, that can be opened and closed with appropriate tools only (e.g.
strap retainer-tension-ring), use sealing rings with a centering ring
- Make sure that the sensor flange is connected to ground, e.g. by having
electrical contact to the grounded vacuum chamber (use metallic clamps)
The transducer may be mounted in any orientation. Mounting with the flange to
the top, however, can lead to early contamination.
An upright orientation with flange to the bottom is to be preferred in order to keep
particles and condensates out of the sensor cell. Further the transducer is
adjusted in the upright position ex works. Different orientation -without readjust-
ment- will lead to reduced accuracy at pressures above 10 mbar.
