50mm Ø Cylinder Probe

A family of flat-ended Cylinder Probes from 2mm to 50mm diameter are available.

The choice of Cylinder Probe is based on whether you wish to perform a puncture/penetration or compression test. For a compression test, the Cylinder Probe needs to be larger than the sample so that during testing the sample is completely contained within the surface are of the probe.

For penetration tests, the choice of small diameter probe will be based on the size of the sample, the force limitation of the Load Cell (a smaller surface area will reduce the measured force) and the lack of homogeneity in the sample. A level of detail might also be required from the sample testing (i.e. smaller Cylinder Probes (usually form 2-4mm diameter) are able to penetrate through layers within a material and show layer detail whereas larger cylinders are more like to compress the layers together during testing. During a puncture test both compressive and shear forces are measured and irrecoverable damage of the sample occurs.

Measurements using Cylinder Probes range from hardness, softness, toughness, stickiness, compactability, compressibility and many other properties.

Additional measurements using large cylinder probes range from visco-elastic creep, Young’s modulus, compliance and stress relaxation.

Self-supporting or contained solid/semi-solid materials.

• Probes with larger diameters have a larger surface area for testing which subsequently requires a high force capacity for testing samples.
• Tests that completely contain a sample provide the ability to measure product springiness/recovery.
• If using this Cylinder Probe as a compression probe where the sample is completely contained under the probe, for comparison purposes the samples need to be of the same size and shape.
