7.1 Safety instructions
CAUTION
Risk of burns due to hot measuring media
The device surface temperature may exceed 70 °C (158 °F),
depending on the measuring medium temperature!
• Before starting work on the device, make sure that it has
cooled sufficiently.
Aggressive or corrosive media may lead to the damage of wetted
parts of the sensor. As a result, measuring medium under
pressure can leak out.
Wear to the flange gasket or process connection gaskets
(e.g. pipe fitting, Tri-clamp, etc.) may caused a pressurized
measuring medium to escape.
When using internal flat gaskets, they can become brittle through
CIP- / SIP processes.
If pressure surges above the permissible nominal pressure of the
device occur permanently during operation, this may affect the
service life of the device.
If there is a chance that safe operation is no longer possible, take
the device out of operation and secure it against unintended
startup.
