Description
Applied Measurements DSCRC low profile tension and compression load cell/pancake load cell is manufactured from stainless steel and is suitable for use in weighing and force measurement applications. They can operate in both tension and compression and are commonly used in materials testing and component fatigue testing applications for axial force measurements where a high accuracy, low-profile device is required.
The high-frequency response of our DSCRC low profile tension and compression load cell also make them ideal for dynamic force and load measurement applications. The high-speed analogue SGA amplifier is an ideal complement to the DSCRC, offering a conditioned signal output of 4-20mA, ±5Vdc or ±10Vdc with a bandwidth of up to 6kHz.
As with all our load cells, the DSCRC low profile tension and compression load cell design can be modified to suit your exact requirements, with alternative threads, custom dimensions and customer-specific capacities.
If you require a rated capacity greater than 0-2kN, the DSCC low profile load cell covers forces from 0-5kN up to 0-1000kN as standard.

How To Install A Pancake Load Cell Guide
Our Applied Measurements experts have put together a 5-step guide to demonstrate how to correctly install a pancake load cell.
Step 1 – Keep the Forces Centrally Aligned
To reduce any off-axis loading, forces must be centrally aligned through the centre of the pancake load cell. We can supply optional load buttons and rod ends which work to reduce any side loading.
Step 2 – Do Not Overtighten the Rod Ends and Load Buttons
When using rod ends and load buttons be sure not to overtighten them when attaching them to the pancake load cell. As this can cause damage to the load cell.
Step 3 – Always Leave a Gap
Ensure that the threads of rod ends or load buttons do not exceed the length of the internal thread in the load cell or mounting base. If a gap is not maintained, the sensing section of the load cell will not be able to move freely when tensile or compressive force is applied, leading to erroneous readings and potential damage.
Step 4 – Mount on a Flat Surface
Always secure the pancake load cell to a clean, flat surface of better than 0.005mm surface flatness.
Step 5 – Contact with Loading Area Only
When installing the pancake load cell ensure the load is applied to the loading area only.
Mounting And Installation Accessories
Load Buttons and Rod End Bearings
Designed to align forces through the principal axis of the load cell thus reducing the effects of extraneous forces, hence offering improved performance from the cell.
Load buttons are used where compressive forces are applied.
Rod End Bearings are used where tensile forces are being applied.

Shape Control for Experimental Continuation
https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.120.254101
By Robin M. Neville, Rainer M. J. Groh, Alberto Pirrera, and Mark Schenk, Phys. Rev. Lett. 120, 254101 – Published 21 June 2018. Available as open access.
Abstract: An experimental method has been developed to locate unstable equilibria of nonlinear structures quasistatically. The technique involves loading a structure by the application of either a force or a displacement at a main actuation point while simultaneously controlling the overall shape using additional bidirectional probe points.[…]
