USA - SIWAREX WL270 K-S CA Compression load cell

Compression Load Cell

The SIWAREX WL270 K-S CA compression load cell is characterized by its very high load class up to 500t and extremely low installation height, making it ideal for container and hopper scales (including for level measurement). In addition to options for expanded load ranges and high temperatures, the load cell also offers options for explosive areas in Zones 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 for a redundant design with a double bridge in the load cells. 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 with Ex protection for Zones 2 and 22 as an option. The deflection of the load cell depends on the rated load and lies between 0.23 and 3.11 mm (0.01 and 0.11 inch).


  • Very low installation dimension

  • Extremely high load classes up to 500t

  • High temperature option up to 250°C and option with double bridge increase application security

Installation Accessories

We offer the following accessories for the compression load cells

Load foot 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.
