Strain Gauged Column and Tester for Load Transfer Verification

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.
