Description
Model F1270 High-capacity load cell up to 300 t
The model F1270 high-capacity load cell is available with rated loads of 7.5 t to 300 t and has been specially developed for application in container and silo weighing technology.
It is also suitable for use in harsh industrial applications and in the construction of testing and production plants, where robustness and long-term stability are required.
With its special geometry this high-capacity load cell is excellently suited for installation in truck scales. Here it automatically aligns itself in such a way that there is no need for complex and precise positioning of the vehicle on the weighing platform.
The use of stainless steel, the welded cover of the strain gauge measuring elements and a glass feed-through for the cable connection allow trouble-free use even under unfavourable ambient conditions.
Due to the integrated radii of the load supports, the installation can be carried out with simple force introduction elements.
Options
- Integrated surge arresters (4 x)
- Accessory mounting kits
