Load versus displacement plots using standard equipment
29 January 2010
RDP Electronics can offer a combination of standard products to provide a simple-to-configure, cost effective system for plotting load versus displacement. Typical applications include materials testing, lifting platforms and vehicle testing.
By using two RDP E725 signal conditioning display units, data outputs from a load cell and from a displacement transducer such as an LVDT, can be combined to present a graphical display of stress over strain on a standard PC or lap top. The RS232 output of the E725 connects to a PC used in conjunction with Microsoft Excel compatible free software downloadable from here.
Designed for use with a wide range of transducers including LVDT, strain gauge and internal in-line types, the E725 signal conditioner and display unit incorporates signal conditioning for transducers, offers a clear 5 digit display with fast peak and trough detection and limit trips shown by indicator lights. The device also offers options such as relay outputs.
