DANGER
Caution: 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
Caution: 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
protective connection according to EN 61010:
· CF connections fulfill this requirement
· For gauges with a KF vacuum connection, use a conductive me-
tallic 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.
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 (® 2 11).
· The gauge is supplied with a built-in grid. For potentially contaminating appli-
cations and to protect the electrodes against light and fast particles, installation
(® 2 17) of the optional baffle is recommended (® 2 47).
· For the vacuum connection sealing, use of a metal seal (® 2 47) is recom-
mended, since elastomer seals (e.g. FPM) can impair the measurement accu-
racy already in the 10
-6
mbar range by outgassing.
· The sensor can be baked at up to 150 °C. At temperatures exceeding 50 °C,
the electronics unit has to be removed (® 2 15) or an extension (Option
® 2 47) has to be installed (® 2 16).
