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
How It Compares
| DEE and DEF S type | The 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 beam | Use the H8C where the load presses down on a deck and the H3 where it hangs from or pulls on the cell. |

Four structures cover nearly every weighing build. Choosing the wrong one creates mounting problems that no amount of calibration will fix.
How To Choose Load Cell Capacity And Accuracy Class
Capacity and accuracy class are the two numbers that decide whether a scale can be built and verified. Here is how to derive both before you commit to a design.
H3 S Type Load Cell Questions
What thread sizes are used?
They change with capacity, from M8 at 25 to 50 kg up to M42 x 3 at 30 t, with UNF threads on the imperial capacities. The full dimensional table is published on this page.
Can the H3 be used for a crane scale?
Yes, it is listed for crane scale, mechanical conversion scale and hopper scale duty.
Which accuracy classes carry OIML approval?
C3 and C4 both carry OIML R60 approval in this family.
