  The SIWAREX WL290 DB-S CA double shear beam load cell is made of nickel-plated specialty steel.

  WL290 DB-S CA load cells are especially suited for large platform and hopper scales. A special mounting unit makes them particularly suitable for assembling scales in vehicles. The double shear beam load cell is installed without oscillation or elastomer force-transmitting mechanisms since transverse forces do not result in the otherwise usual oscillating or deflection effects in the load cell.

  Load cells are legal-for-trade according to OIML R60. They are available in accuracy class C3.

  Дизайн

  The measuring element is a spring body made of special steel. Due to the galvanic coating of nickel and the IP67 degree of protection it is suitable for use in harsh environments.
