Applications

Where the WST404 Works Best

Tension / Compression Testing

Inline force measurement in test rigs, materials testing machines and pull-push fixtures. The WST404 reads in both directions with matched output.

OIML-grade linearity

Crane Scales & Hoist Weighing

Suspended from hooks, shackles or crane blocks, the WST404 provides safe dynamic load readout for steel mills, scrap yards and shipping terminals.

multiple capacity options capacity

Hopper / Tank Weighing

Inline mounting between structure and vessel converts net contents into a weight signal. Compatible with most weighing indicators and batching controllers.

IP-rated sealing

Electrical Notes

  • Shielded cable; keep away from motor/power runs, ground the shield at the indicator side

Mounting Checklist

  1. Mount on a rigid, flat base
  2. Torque mounting screws evenly; avoid over-torque that preloads the measuring element
  3. Keep the load applied through the intended loading axis; verify alignment before calibration
  4. Verify zero balance before calibration, then calibrate with certified test weights
