Description
Compression load cell PR 6201 and mounting kits PR 6001, PR 614x
The high-load weighing solution for silo and vessel weighing
The load cell from the PR 6201 series has been specially designed for high-load weighing of silos and tanks. Its unique construction principle, in conjunction with the FlexLock mounting kits, makes it possible to compensate for movements with a negligible effect on the weighing result.
Unrivalled reliability, robustness and stability for your silo weighing
- For unusually large and heavy silos with maximum capacities from 100 t to 520 t.
- With the FlexLock mounting kits, it is possible to compensate for movements arising from mechanical or thermal contraction or expansion of the container or the support structure.
- Thanks to the use of stainless steel and the top IP68/ IP69 protection class, the cell holds its own even in adverse conditions.
- For maximum capacities of 500 kg to 200 t, a direct 4…20 mA analogue output is optionally available.
