Equipment variants
All force transducers are available in different versions. The following options are avail­
able:
1. Nominal (rated) force:
You can purchase nominal (rated) forces from 1.2 5kN to 1.2 5MN.
2. Double bridge design
The force transducer is also available with two electrically isolated measurement
bridge circuits.
3. Adjusted rated output
On request, we can adjust the rated output of your U10M to exactly match the nominal
rated output. In sensors with nominal (rated) forces 1.25kN, 2.5kN and 5kN, the out­
put signal at nominal (rated) force is then 1mV/V, in all other force transducers it is
2mV/V. These values apply together with 100% calibration (standard). If you choose
the 200% calibration option, the output signal doubles. If you order the "adjusted rated
output" option, the output resistance is always adjusted as well, so that several sen­
sors can be connected in parallel. (Exception: nominal (rated) force 1.25MN is not
suitable for parallel connection)
4. Calibration
On request, HBM can calibrate the force transducer to 200% nominal (rated) force.
The high mechanical reserves of the force transducer make this application possible
in measurement tasks with a limited oscillation bandwidth (see Specifications). But be
aware that when double the force is measured, the output signal also doubles.
5. TEDS transducer identification
You can purchase the force transducer with transducer identification ("TEDS"). TEDS
(Transducer Electronic Data Sheet) allows you to store the transducer data (rated out­
puts) in a chip, that can be read out by a connected measuring device. Each measur­
ing bridge has a separate TEDS in the double bridge variant.

6. Without adapter
You can purchase the force transducer without an adapter. The force transducer can
then be directly screwed onto a structural element using the pitch circle,
see Fig. 3.1.
