MoE Accessories and Compressometers

Compressometer/extensometer model 55-C0221/D fitted with two digital gauges 25x0,001 mm
Compression strength is commonly used to evaluate concrete performance; Elastic Modulus (or Modulus Of Elasticity) value, reflecting the ability of concrete to deform elastically under a given load, is also becoming increasingly necessary to be assessed in order to avoid excessive deformations and sway in structures allowed to deflect by a certain amount (skyscrapers, bridges, etc.) and to satisfy serviceability requirements.

Axial-Circumferential Compression Device

The compressometer / extensometer for static Modulus of Elasticity and Poisson's Ratio

Standards ASTM C469

Compressometer/extensometer model 55-C0221/E fitted with two high precision displacement transducers LDT type, 0.001mm x 10mm
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 (C0221/E and C0221/D) and dia.100×200 mm (C0221/F) concrete cylinders, or core, subjected to axial loading. It works by measuring the relative displacement of datum points on the cylinder surface.

The available models are:
  • 55-C0221/D fitted with two digital gauges 25×0,001 mm.
  • 55-C0221/E and 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 our Automatic control consoles MCC or Automax Multitest which can provide cyclic loading and automatic determination of the Modulus of Elasticity.
The data logger  as, for example, our 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. Please get in touch with our technicians for complete information and service

NOTE:
  • the model fitted with displacement transducers can be connected to our readout and control units AUTOMAX Multitest and MCC or to our multichannels datalogger
  • the model fitted with digital dial gauges can download readings to a PC with a dedicated cable (see accessories).

 

 

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.

Compressometer-Extensometer for Elastic Modulus Determination

Aluminium and steel structure incorporating a high precision inductive transducer.

Standards ASTM C469 ISO 6784 DIN 1048 UNI 6556 BS 1924:1 BS 1881:121 EN 13412 EN 12390-13

Three compressometer-extensometers 55-C0222/H fitted to a cylindrical specimen during compression stage.
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 Automax Multitest which can provide cyclic loading and automatic determination of the Modulus of Elasticity.
A data logger  as, for example, our model 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. Please get in touch with our technicians for complete information and service.
Main Features

Strain Gauges

They provide a very accurate electrical signal, strictly proportional to the strain of the specimen

Standards ASTM D5407 ASTM C469 ISO 6784 DIN 1048 UNI 6556 BS 1881:121 EN 13412 EN 12390-13

Rock sample fitted with 82-P0390 strain gauges
Description
They provide a very accurate electrical signal, strictly proportional to the strain of the specimen submitted to load application, for determining the Elastic Modulus and strength characteristics as alternative to the Compressometer-Extensometers 55-C0222/G which can be used only on samples  with min dia.75mm and min height 160mm. They can be applied to the specimen surface by a special Adhesive-Catalyst agent and other accessories all included in the 82-P0399/C Strain gauge application kit.
Up to 4 strain gauges ¼ bridge, and up to 8 ½ bridge, can be directly connected by one or two interfaces 82-P0398  to to our automatic control consoles  MCC or Automax Multitest which are suitable for cyclic loading and automatic determination of the Modulus of Elasticity.
Strain gauges can also be connected, by one or two interfaces 82-P0398, to a suitable data logger as, for example, our model 82-P9008, when the load application on the specimen is performed with Automatic compression testers as, for example the AUTOMAX PRO and PILOT PRO models. In this case, one of the channels of the Datalog 82-P9008 should be used for the load signal coming from an additional pressure transducer with selecting valve fitted to the compression tester.
