3.1 Vacuum Connection
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
The transmitter 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 transmitters 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.
The transmitter may be mounted in any orientation. To keep conden-
sates and particles from getting into the measuring chamber, preferably
choose a horizontal to upright position. See dimensional drawing for
space requirements (→ 11).
When installing the transmitter, make sure that the area around the
connector is accessible for the tools required for adjustment while the
transmitter is mounted (→ 37).
When installing the transmitter, allow for installing/deinstalling the
connectors and accommodation of cable loops.
• The transmitter is supplied with a built-in grid. For potentially contaminating
applications and to protect the electrodes against light and fast charged
particles, installation (→ 15) of the optional baffle is recommended (→ 43).
• The sensor can be baked at up to 150 °C. At temperatures exceeding 50 °C,
the electronics unit has to be removed (→ 14) or an extension (Option
→ 43) has to be installed.
