Do not hold OPTISWITCH 5100 C, 5150 C on the tuning fork.
Particularly with flange or tube versions, the tuning fork can be
damaged by the instrument weight. Transport coated instru-
ments very carefully and avoid touching the tuning fork.
Remove the protective cover just before mounting.
The process fitting must be sealed if there is gauge or low
pressure in the vessel. Before use, check if the seal material is
resistant against the measured product and the process
temperature.
The max. permissible pressure is stated in the "Technical
data" in the "Supplement" or on the type label of the sensor.
The vibrating level switch is a measuring instrument and must
be treated accordingly. Bending the vibrating element will
destroy the instrument.
Warning:
The housing must not be used to screw in the instrument!
Applying tightening force on the housing can damage its
internal mechanical parts.
To screw in, use the hexagon above the thread.
