Application

SIWAREX WP231 is the optimum solution wherever load cells are used for measuring tasks. The following are typical SIWAREX WP231 applications:

• Non-automatic weighing instruments, also legal for trade
• Fill level monitoring of silos and bunkers
• Measuring of crane and cable loads
• Load measuring for industrial lifts and rolling mills
• Scales in zone 2 hazardous areas
• Force measuring, hopper scales, platform scales and crane scales

Function

The primary task of SIWAREX WP231 is the measurement and conversion of sensor voltage into a weight value. Up to three interpolation points are used for the weight calculation.

Weighing functions

There are commands available for zeroing and taring. Engineers can activate up to three different tare default values for this.

SIWAREX WP231 is factory-calibrated. This means you can automatically adjust the scale without adjustment weights, and you can replace modules without the need to readjust the scale.
