Product-specific hazards

2.9.1

Sensor design

Danger! The sensor may only be removed when the housing is in «Maintenance» position
(retracted/withdrawn) and the ball valve is closed, since if the electrode/sensor is missing from
the housing, there will be path for the process medium to escape to the envi ronment.
This can endanger personnel and cause damage to the environment and material. Toxic or
aggressive media can pose a threat to human life through poisoning, chemical burns or scal-
ding.
Attention: If an electrode/sensor is broken, it must be replaced immediately.
Danger! A broken sensor jeopardizes process safety, since it is not then possible to achieve
reliable measurement results.
Gefahr: The sensor may only be removed when the housing is in «Maintenance» position and
the ball valve is closed.
Gefahr: The housing may only be moved to the «Measuring» position when a sensor is fitted
and the ball valve is open.
Principally, personal protective equipment such as protective goggles and clothing must be
worn.
Any manipulation of the electrode/sensor may only be carried out when the retractable housing
is in the retracted/withdrawn position («Maintenance» position) and the ball valve is closed.
