Description
Model F3841 Shear beam
With integrated amplifier, up to 10,000 kg [22,046 lb]
The model F3841 shear beam is a variant of the model F3831 shear beam that is amplified to an 4 … 20 mA output signal.
The integration of the amplifier into the existing case eliminates the use of a cable amplifier.
The electromagnetic compatibility (EMC) is higher as well.
The instrument is suitable for precise static and dynamic force measurement in tension and compression force direction.
It is ideal for measuring shear forces and weight in a variety of application areas.
The instrument is used in industrial weighing and laboratory technology, in the agricultural sector and in the process industry.
Mounting is carried out directly between the object to be weighed and the fastening, ensuring a reliable and stable force transmission.
For use on platforms, various load feet and mounting kits are available, which enable flexible integration into different system environments.
Depending on the application, corresponding approvals are available.
