VEGAFLEX 86 • Modbus and Levelmaster protocol

41848-EN-130314

Information:

The distance piece must only be incorporated up to max. 50 mm (2 in)

in the vessel isolation. Only then, a reliable temperature decoupling is

guaranteed.

If there is a danger of the cable probe touching the vessel wall during

operation due to product movements or agitators etc., the measuring

probe should be securely fixed.
In the gravity weight there is an internal thread (M8), e.g. for an eye-

bolt (optional) - (article no. 2.1512).
Make sure that the probe cable is not completely taut. Avoid tensile

loads on the cable.
Avoid undefined vessel connections, i.e. the connection must be

either grounded reliably or isolated reliably. Any undefined change of

this requirement can lead to measurement errors.

In case of difficult installation conditions, the probe can be also

mounted laterally. For this purpose, adapt the rod with rod extensions

or bow-shaped segments.
Let the probe length determine automatically by the instrument to

compensate the resulting running time changes.
The determine probe length can deviate from the actual probe length

when using bow-shaped segments.
Make sure that the rod of the probe is at least 300 mm (11.811 in)

away from the vessel wall
