Siemens SIWAREX WL250 ST-S SA Load Cell


Siemens SIWAREX WL250 ST-S SA Load Cell is designed to handle both tension and compression loads in an s-type arrangement. It’s worth noting that its primary measurement orientation is tension, and it comes from the factory with calibration optimized for tension applications. For compression applications, it may not guarantee adherence to the specified characteristic values and error limits.
