1.2.8 Scaling

There are three types of min./max. values:
1 The measuring range
The maximum sensor performance is in this range. Values outside of
the measuring range are displayed via messages, for example. Refer
to table (see below) for the measuring range.
2 Standard scaling
The output signals are assigned to this measuring range as standard:
- during delivery if no entries are made in the order code
- after exchanging the unit, the measuring range recorded in the
instrument is applied as standard.
Refer to table (see below) for the measuring range.
3 The maximum settings for the manual scaling
- the values are not expressly given in the table. The maximum limits
can be calculated as follows:
X = difference between MIN. and MAX. value of the standard scaling
(Max. value of standard) + (50 % of X)
(Min. value of standard) - (50 % of X)
- It is thus possible to scale beyond the measuring range, e.g. for the
adjustment of the scaling limits to standard values of a PLC.
However, the physical measurement range limits are the deciding
factor when defining alarms.
- 1.2 Product description
The transmitter even retains its scaling with the voltage
disconnected.
