3.2 Vacuum Connection
Dirt and damage, especially at the vacuum flange, have an ad-
verse effect on the function of this vacuum component.
Please take account of the necessary instructions with regard to
cleanliness and damage prevention when using vacuum compo-
nents.
-
Remove the protective cover (is required again during maintenance work!)
- Make vacuum connection via small flange DN40 ISO KF (VSH88) or conflat
flange DN40CF (VSH89)
- 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 and malfunction.
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
readjustment- will lead to reduced accuracy at pressures above 20 mbar.
