    -MODULUS OF ELASTICITY
    -UNIAXIAL SECANT ELASTIC MODULUS
  • High sensitivity: 0.02 micron
  • Suitable for various sample size: cylinders up to dia. 160x320mm, cubes up to 200 mm, prisms 40x40x160 mm etc.
  • Easy and quick application to the specimen
  • Can be directly connected to our Automatic control consoles MCC8 and ADVANTEST 9
General description
General description
Aluminium and steel structure incorporating a high precision inductive transducer. Three units are generally recommended for axial deformation measurement. They can be easily applied to the specimen by a pair of elastic bands supplied as standard.  It has to be connected to a suitable data logger or, directly to our Automatic control consoles MCC or ADVANTEST which can provide cyclic loading and automatic determination of the Modulus of Elasticity.
A data logger  as, for example, our model 82-P9008 http://www.controls-group.com/eng/general-lab-testing-equipment/data-acquisition-unit-datalog-8.php, can be  used with compression testers for axial deformation measurement when it's not mandatory to perform loading / unloading cycles, but only loading ramps. In this case, one of the channel of the data logger should be used for the load signal coming from an additional pressure transducer with 3 way connector fitted to the compression tester. Please get in touch with our technicians for complete information and service.
