Axial-Circumferential compressometer/extensometer

The compressometer/extensometer for static Modulus of Elasticity and Poisson’s Ratio is a device for measuring the longitudinal and diametrical strain.

The compressometer/extensometer for static Modulus of Elasticity and Poisson’s Ratio, as defined by ASTM C469, is a device for measuring the longitudinal strain and corresponding diametrical strain of dia. 150 x 300 mm (6″x12″) and dia. 100 x 200 mm (4×8″) concrete cylinders, or core, subjected to axial loading. It works by measuring the relative displacement of datum points on the cylinder surface.

Models

• 55-C0221/D fitted with two digital gauges 25×0,001 mm.
• 55-C0221/E and 55-C0221/F fitted with two high precision displacement transducers LDT type, 0,001mm x 10mm.

The models fitted with displacement transducers can be connected to a suitable data logger or directly to Automatic control consoles (as MCC or Automax Ultimate) which can provide cyclic loading and automatic determination of the Modulus of Elasticity.

The data logger as, for example, the mode 82-P9008, 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.

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.

NOTE:

The model fitted with digital dial gauges can download readings to a PC with a dedicated cable
