Calibration of Compression and Flexural Machines

Digimax Plus 82-P0801/E (in the middle) with 3000 kN load cell 82-E0100/300 and 82-P0172/M printer
We propose a comprehensive range of measuring instruments for force verification and calibration of various testing machines. It includes load cells, ranging from 5 kN to 5,000 kN, digital indicators for force verification and for load transfer verification according to the main International Standard. Traceable calibration certificate for load cells should be purchased when they are first connected to a digital indicator. As an alternative, the official ACCREDIA calibration certificate can be purchased instead.

Digimax Plus 82-P0801/E (in the middle) with 3000 kN load cell 82-E0100/300 and 82-P0172/M printer
Description

 

The system, connected to any strain gauge load cell, provides data for the force verification of the testing machine. Data can be printed by a standard serial printer as, for example, our model 82-P0172  with serial cable 82-P0172/1 (see accessories), or unloaded to PC for processing and, by the relevant MS Excel template 82-P0804/E4 (see accessories), for producing the test certificate conforming to the standard in use as, for example, EN 12390-4 or ASTM C39 for concrete compression testers.
The Digimax Plus, connected to one of our load cells 82-E0100/30 to 82-E01000/500 can be supplied complete with Official or Traceable calibration certificate. See ordering information. Each cell has to be calibrated separately and the certificate refer to one cell only

Strain Gauged Column and Tester for Load Transfer Verification

Strain-gauged load cell and digital redout unit Accuracy of force indication

Standards EN 12390-4

Description

Introduction
The verification of force transfer includes:

  • Accuracy of force indication
  • Self alignement of the upper machine plate
  • Alignement of the upper machine plate
  • Restraint of movement of the upper plate

These verifications can be performed using the 82-E0105/1 strain gauged cell, connected to the 82-P0804/E tester . The processing of data can be automatically performed with a PC with the testing software 82- P0804/E1, E2, E3 and E4 (see accessories).

Description of 82-E0105/1 cell
The device consists of a 3000 kN cap. strain gauged column, 100 mm dia., 200 mm high with hardness and tolerances conforming to standards. The column is gauged with matched temperature compensated electrical resistance strain gauges. Four complete bridges, each centred at one of the ends of a pair of orthogonal diameters half- way up the cylinder are applied. Each bridge consists of two elements measuring axial strain and two measuring circumferential strain.
The column is supplied complete with auxiliary platen and spacers for easy and precise placing of the column either centrally or 6 mm displaced from the centre. The column can also be used as a standard load cell to test the accuracy of force indication.
It has to be used with dedicated strain measuring apparatus as, for example, our model 82-P0804/E.

Description of 82-P0804/E
This tester, when connected to the 82-E0105/1 column, to a PC and printer using the specific software 82-P0804/E1 and 82-P0804/E2, provides completely automatic data acquisition, processing and print of the verification test certificates concerning either the accuracy of force indication or the other force transfer verifications. During operation, acquired data are displayed on the graphic screen and then downloaded by the serial port to PC and printer .The system can also be used directly connected to a simple 24 column serial printer (e.g. our model 82-P0172) or to download the test results for further processing using programs developed by the user.
Supplied complete with carrying case.

Main Features
  • One cell only, 3000 kN cap., to test either the force accuracy and force transfer
  • Digital tester also connectable to other cells
  • Tester and column can be supplied with official calibration certificate issued by a European   accreditation laboratory
  • Suitable for calibration of Class 1 compression testers
