Compression Load Cells

Compression load cells are ideal for applications such as tank weighing, mounting under mixers or vessel weighing and are ideally suited to applications ranging from 1000kg through to 100,000kg. There are a range of load cell mounts to interface between the item needing to be weighed and the load cell itself.

Compression Load Cell FAQs

What are common failure modes?

Overloads, misalignment (bending), cable damage, ingress and corrosion. Correct mounting, protective hardware and routine inspections reduces failures exponentially. Most failures are due to poor installation

Do compression load cells need calibration?

Yes — initial load cell calibration on installation and periodic calibrations are essential, especially for legal-for-trade or safety-critical applications.

Are compression cells suitable for outdoor/washdown use?

Yes — stainless steel versions with high IP ratings are available for corrosive, wet or hygienic environments. We have models that can also withstand higher temperatures.

Can they handle side loads?

They prefer strictly axial loads. For environments with lateral forces, use guides, load-distribution plates or a model designed to tolerate off-axis loads, these are built into the purpose made installation mounts.

How should they be mounted?

Use manufacturer-recommended installation mounts, centring rings or load buttons; ensure axial alignment to avoid bending. Proper torquing and isolation from side loads are important. Each compression load cell generally has a matched mount to be installed into.

Are compression load cells accurate?

Yes — accuracy depends on model and class. Look at data sheets for non-linearity, hysteresis and accuracy classes (e.g., C3/C4) for performance expectations. Typical accuracies are around 0.02% of full capacity, installation is always the key to maximum performance, load cell accuracy cannot outperform and poor installation.

How do I choose the right capacity?

Select a cell rated above your maximum expected load with margin for overloads and dynamic peaks. Also consider resolution and required accuracy. You need to decide how many load cells you will need and the total capacity with margin for error, the sum of the sum of the load cells should be greater than the expected total load.

For Example, on a three legged vessel rated to 15t total weight you would select 3 x 7.5t load cells, not 3 x 5t load cells.

What shapes do they come in?

Column/rod, puck/button, disc/pancake, and platform/flanged housings — each tailored to capacity, height constraints, or installation needs.

Where are compression load cells used?

Commonly in testing machines, hydraulic presses, platform and tank weighing, structural load monitoring, and OEM machinery where compressive loads are dominant.

What is a compression load cell?

A sensor that measures compressive (pushing) forces by converting mechanical strain into an electrical signal using strain gauges.
