DANGER
DANGER: overpressure in the vacuum system >1 bar
Injury caused by released parts and harm caused by escaping process
gases can result if clamps are opened while the vacuum system is
pressurized.
Do not open any clamps while the vacuum system is pressurized. Use
the type of clamps which are suited to overpressure.
DANGER
DANGER: overpressure in the vacuum system >2.5 bar
KF flange connections with elastomer seals (e.g. O-rings) cannot
withstand such pressures. Process media can thus leak and possibly
damage your health.
Use O-rings provided with an outer centering ring.
DANGER
The gauge must be electrically connected to the grounded vacuum
chamber. This connection must conform to the requirements of a pro-
tective connection according to EN 61010:
• CF connections fulfill this requirement
For gauges with a KF vacuum connection, use a conductive metallic
clamping ring.
Caution
Caution: vacuum component
Dirt and damages impair the function of the vacuum component.
When handling vacuum components, take appropriate measures to
ensure cleanliness and prevent damages.
Caution
Caution: dirt sensitive area
Touching the product or parts thereof with bare hands increases the
desorption rate.
Always wear clean, lint-free gloves and use clean tools when working
in this area.
The gauge may be mounted in any orientation. To keep condensates
and particles from getting into the measuring chamber, preferably
choose a horizontal to upright position. See dimensional drawing for
space requirements (
→ 12).
• The gauge is supplied with a built-in grid. For potentially contaminating appli-
cations and to protect the electrodes against light and fast charged particles, in-
stallation (
→ 16) of the optional baffle is recommended (→ 50).
• The sensor can be baked at up to 80 °C (at vacuum connection, horizontally
mounted). At temperatures exceeding 50 °C, the electronics unit has to be re-
moved (
→ 15).
