KROHNE OPTISWITCH 3000C Transistor EN - Manual (Page 9)

4 Mounting
4.1 General instructions
In general, OPTISWITCH 3000 C can be mounted in any
position. The instrument must be mounted in such a way that
the vibrating element is at the height of the requested switching
point.
Use the recommended cables (see chapter "Connecting to
power supply") and tighten the cable gland.
You can give your OPTISWITCH 3000 C additional protection
against moisture penetration by leading the connection cable
downward in front of the cable entry. Rain and condensation
water can thus drain off. This applies mainly to mounting
outdoors, in areas where moisture is expected (e.g. by
cleaning processes) or on cooled or heated vessels.
Fig. 2: Measures against moisture penetration
Do not hold OPTISWITCH 3000 C on the vibrating element.
The sensor can be damaged by the weight of the instrument.
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.
