Load Cells

H3 S Type Load Cell

Wide range S type cell from 25 kg to 30 t with OIML R60 C3 and C4 approval.

Product Overview

The H3 is the widest S type family in this catalogue, covering 25 kg to 30 t in metric and 100 lb to 20 Klb in imperial. Its S beam design accepts tension, compression or both, which is why it appears in crane scales, mechanical scale conversions, hopper scales and a long list of one off weighing devices. Dimensional tables are published per capacity band so the mounting can be designed before the cell arrives.

Materials And Construction

  • Alloy steel body
  • Adhesive sealed internals

Customisation Options

  • Metric or imperial capacity and thread form
  • Accuracy class from C2 to C4
  • Cable length on request

Use Guide

  • Check the dimensional table for your capacity band before machining brackets, since thread form changes with capacity
  • Use rod ends or clevis fittings so the load stays on the loading axis
  • Do not exceed the 150 percent safe overload in normal operation

Certification

  • OIML R60 C3
  • OIML R60 C4
Comparison

How It Compares

Compared with alternatives in this catalogue
DEE and DEF S typeThe DEE and DEF cover 100 kg to 5 t with IP68 above 1.2 t. The H3 covers a much wider band and adds OIML R60 C3 and C4 approval.
H8C shear beamUse the H8C where the load presses down on a deck and the H3 where it hangs from or pulls on the cell.
