Every unit is factory calibrated and inspected before dispatch; parameters on this page reflect shipped goods.
Inline force measurement in test rigs, materials testing machines and pull-push fixtures. The WST405 reads in both directions with matched output.
OIML-grade linearity
Suspended from hooks, shackles or crane blocks, the WST405 provides safe dynamic load readout for steel mills, scrap yards and shipping terminals.
multiple capacity options capacity
Inline mounting between structure and vessel converts net contents into a weight signal. Compatible with most weighing indicators and batching controllers.
