SM-217 | Steel Beam Flexural Testing Assembly and Strain Gauges with Data Acquisition System

A steel test beam with W-section. Rigid reaction frame for loading with hydraulic jack and dial gauge.  Capability of simulating various support conditions.  Set of strain gauges, data loggers, cables, adhesives and related accessories. The versatile Flexural Testing Frames are designed for minimum deflection at maximum load resulting in very high accuracy. The load frame is a fabrication carrying the ram fitted to the upper crosshead. The frames have a single acting down stroking ram. The return of the ram is done by spring to get maximum accuracy on the load measurement. A Wheatstone bridge/strain gauges is used for load measurements. Flexural Frames models are designed to allow easy and practical front loading of the specimens. It provides the advantage of being able to perform flexural tests on longer specimens. The load frame provides the stability needed for accurate and repeatable test re­sults.

Software

Microcontroller based electronics system fully instrumented and computer controlled via USB / Ethernet interface /WiFi to record / set process parameters. (Computer not include). The experiments are carried out more effectively. The final result reliability is much higher without doubt, therefore the work done by the researcher possess a higher credibility.

Data Storage

The data are stored in a data base either in file format supported by third party software. The data can be represented both numeric format or graphic format like their trends and distributions independently the way it is used. As being available for the users anytime allows different tests to be compared and reach conclusion more truthful.
