Controls Group Axial-circumferential compression device Axial-circumferential compression device

Axial-circumferential compression device

Main features
  • Ideal for axial deformation and diametrical extension measurement.
  • Suitable for dia.150x300mm (6"x12") and dia.100x200mm (4"x8") cylinders.
  • Easy and quick application to the specimen.
  • Two different types of measuring systems are available:digital dial gauges or high precision displacement transducers LDT type. 
  • the model fitted with displacement transducers can be connected to our readout and control units AUTOMAX E MODULUS, MCC series and ADVANTEST or to our multichannels datalogger (see accessories and additional information for the proper configuration);
  • the model fitted with digital dial gauges can download readings to a PC with a dedicated cable (see accessories).
General description
General description
The compressometer / extensometer for static Modulus of Elasticity and Poisson’s Ratio to ASTM C469 is a device for measuring the longitudinal strain and corresponding diametrical strain of dia.150x300mm (6"x12") and dia.100x200 mm (4x8") concrete cylinders, or core, subjected to axial loading. It works by measuring the relative displacement of datum points on the cylinder surface.
