General description
General description
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. The specimen has to be loaded by a suitable Flexural frame as, for instance, our models 50-C1511/FR or 50-C1601/FR, and a control console capable of applying load under displacement control as our model Advantest 9 or MCC MULTITEST.

The test shall be performed under displacement control. This is the reason why we propose the ADVANTEST 9 50-C9842 or MCC Multitest 50-C8422/M Control consoles. See MCC, multifunctional control console, ADVANTEST 9, Servo-hydraulic control console
