4 Mounting

4.1 General instructions

In general, OPTISWITCH 3100 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 cable (see chapter "Connecting to

power supply") and tighten the cable gland.

You can give your OPTISWITCH 3100 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.

Do not hold OPTISWITCH 3100 C on the vibrating element.

Especially with ﬂange and tube versions, 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 vibrating level switch is a measuring instrument and must

be treated accordingly. Bending the vibrating element will

destroy the instrument.
