UDA Aluminium Compression Load Cell
Aluminium compression cell for platform scales and compression testing, 50 kg to 800 kg.
Product Overview
The UDA is a compact aluminium compression cell covering 50 kg to 800 kg in accuracy class C3. It is specified for platform scales and for all kinds of compression testing devices, where a light, rigid cell with a defined installation torque matters more than heavy capacity.

Materials And Construction
- Aluminium body
Customisation Options
- Capacity selected from the published range
- Cable length on request
Use Guide
- Tighten to the recommended 25 Nm installation torque so units behave consistently
- Keep the load purely compressive and axial; this cell is not intended for tension
- Protect from direct washing, since protection is IP65 rather than IP67 or IP68
Certification
- Accuracy class C3
How It Compares
| L6 single point families | Single point cells carry a whole platform within a published deck size; the UDA is a compression cell used where the mechanical design already defines the load path. |
|---|---|
| SQB shear beam | The SQB is a steel beam cell from 0.25 t upward with IP67 and IP68 options; the UDA is the lighter aluminium option below 1 t at IP65. |

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.
UDA Aluminium Compression Load Cell Questions
Can the UDA be used in tension?
No. It is a compression cell. For tension use an S type cell such as the H3 or the DEE and DEF family.
Is the UDA suitable for wet areas?
It is IP65, which covers water jets but not immersion. For washdown areas choose a sealed stainless steel cell.
What accuracy class is available?
C3, with creep error within ±166 ppm over 30 minutes and zero balance within ±3 percent of Emax.
