The compression load cell SIWAREX WL270 K-S CA is characterized by its very high load class up to 500t and its extremely low installation height - the reasons why it is particularly suitable for implementation in container and hopper scales, e.g. for level measurement. Beside the existing options for expanded load ranges and high temperatures this compression load cell is now also available as option for explosive areas in zone 2 and 22.

Typical applications: 


Use in extreme temperatures up to 250°C
This load cell features options for expanded temperature ranges, for all rated loads.The specially developed strain gauges can be used in a temperature range from -30 °C to 250 °C without any damage. Cables and accessories are appropriately adapted to these temperature ranges. 


More application security with a double bridge 
Applications such as cranes require high security standards. SIWAREX WL270 K-S CA offers an option with a double bridge in the load cells in redundant design. Both measuring bridges deliver continuous measurement values, which make it possible to check for any discrepancies during the weighing process. If one bridge is damaged, the second bridge continues to work 
This option is available for loads of 13t or greater. 
An enclosure made of painted steel protects the strain gauge from environmental influences.


Use in explosive areas
The load cell is also available as option with ex-protection for zone 2, 22 available.

The deflection of the load cell depends on the rated load and lies between 0,23 and 3,11mm (0.01 und 0.11 inch).


For our compression load cells we offer following installation accessories

Self-aligning bearing SIWAREX WL270 K-S CA

The self-centering self-aligning bearing for SIWAREX WL270 K-S CA load cells comprises two pressure plates that together with the load cell form a self-centering unit. This allows the top plate, and thus the load bearing implement, to accommodate horizontal displacements (e.g. due to temperature fluctuations).

The load cell is not included in the scope of delivery of the self-aligning bearing.
