Weighing module SIWAREX MS

Description

The SIWAREX MS is a compact weighing electronics for the system S7-200 from SIMATIC. The data for the actual weight can be accessed directly in the SIMATIC CPU without the need for any additional interfaces. SIWAREX MS is the optimum solution wherever strain gauge sensors, such as load cells, force sensors or torque measuring shafts, are used for measuring tasks.

The following are typical SIWAREX MS applications: Non-automatic weighing machines, Simple discontinuous weighing processes, Fill level monitoring of silos and bunkers, Measuring of crane and cable loads , Load measuring for industrial lifts and rolling mills, Weighing in potentially explosive areas (zone 2 or zone 1 using Ex interface SIWAREX IS or Pi) , Monitoring of belt tension, Force measuring, weighing hoppers, platform scales and crane scales.
