products. These blocking distances for different mediums are listed
in chapter "Technical data". Keep in mind for the adjustment that the
default setting for the measuring range refers to water.
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 specified in chapter "Technical
data" or on the type label of the sensor.
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 (M12), e.g. for an eye-
bolt (optional) - (article no. 2.27423).
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, for example in a socket, the
probe can be adapted respectively with a rod extension.
Let the probe length determine automatically by the instrument to
compensate the resulting running time changes.
You can find further information in the supplementary instructions of
the rod extension.
