7.3.3 Inductive transducers
Inductive transducers (for example force transducer from HBM) are passive
transducers that have the following features:
S They must be supplied with an excitation voltage (carrier frequency)
S They are inductive half or full bridge circuits
S The transducer is identified by the following data:
- Nominal (rated) displacement (for example 20 mm)
- Nominal (rated) sensitivity (for example 10 mV/V)
The standard setting for the excitation voltage U
B
with inductive transducers
is 2.5 V. If higher measuring ranges are required or multiple transducers are
connected in parallel, a lower excitation voltage must be selected. The indi
vidual values depend on which module is used.

ML55B 1.5...45.9 3.0...91.8 7.5...229.5
With these measuring range limits, depending on the setting, a voltage of
1V ... 10 V can be generated on the analog output.

The specified full scale values are maximum values that cannot be affected
by settings of the analog output!
