Description

Our CCDDT column load cells include are specifically engineered dome top to mitigate the effects of eccentric or off-axis loading. The spherical top surface acts as a pivot, self-aligning the point of force application to the central axis of the load cell’s internal strain gauges. This design significantly improves measurement accuracy by reducing the shear forces that can lead to measurement errors when a load is not perfectly centered. However, for many applications, a flat, stable surface for load application is required. This is where our load caps become essential.

Technical Purpose of a Load Cap

A load cap is a component designed to interface between the load and the domed-top load cell. The underside of the cap features a concave spherical recess that mates with the convex dome of the load cell. This allows the cap to rock or pivot, preserving the self-aligning function of the domed top.

The top surface of the cap provides a flat, stable plane, which is critical for:

• Uniform Load Distribution: Distributing the compressive force evenly across the contact area.
• Stable Interface: Providing a secure point of contact for tanks, platforms, or other structural components.
• Preventing Damage: Shielding the sensitive domed surface of the load cell from direct impact, wear, and potential damage from uneven or sharp load points.

In essence, the load cap bridges the gap between the domed cell’s inherent self-aligning accuracy and the practical requirement for a flat loading surface, ensuring both optimal performance and longevity of the sensor.
