Displacement Transducer for Measurement of Crack Opening


This transducer is used for determining the Crack Mouth Opening Displacement (CMOD) conforming to EN 14651. The transducer have to be positioned over the notch sawn previously into the test beam.
This test has to be performed with a suitable flexural frame having proper stiffness and capacity as, for instance, our models 50-C15xx/FR or 50-C17xx/FR, and a control console capable of applying load in displacement control as our model MCC or Automax Multitest.
