WDW-30 Computer Controlled Geo-textile Testing machine

1. Introduction

The geo-textile testing machine is mainly used to do the tension, compression, bursting, puncture test of glass fiber geo-textile, plastic geo-textile, geosynthetics, geogrid, etc. Its precision auto control and data collection system can realize the full digital adjustment to data collection and control process. In the test, the max bearing force, compression force, tensile strength, compression strength, elongation, deformation can be measured and then displayed and calculated by the computer according to the parameters set before the test when test finishes.

2. Main features

1) With remote control box, the crossbeam can move up and down quickly and conveniently.

2) Can return to the original place when test is over, intelligent, reliable and safe.

3) Has the functions of safe protection, eg, limit position protection, over load protection, over current protection.

4) The test data can be saved, enquired and used from its strong database

5) Can realize the following control mode: constant stress control, constant deformation control, constant strain control, constant stroke control, constant load control, constant elongation control, constant displacement control, etc. Also, the customer can set the control mode themselves.

6) Can changeover the test curves displaying, the test curves including stress-strain curve, force-deformation curve, force-displacement curve, force-time curve, deformation-time curve, displacement-time curve, force-strain curve and the curves can be enlarged and compared.
