Overview
The ST500 extensometer is designed for high resolution measurement of high forces and deformations of structures, presses, tanks, bridges, frames, etc... The sensor consists of a strain gauge fully wired and then pressurized on a test body through the housing.
The measuring range is 500µm/m. Technically comparable to a direct application of strain gauges on the structure, this extensometer brings a gain in simplicity of implementation and flexibility, while offering a measurement characterized by a high resolution, very low drift effects and an excellent response time.
Mounting and use
The housing is positioned with 4 M6 screws. The surface must be flat and clean before applying the extensometer.
Dimensions

The strain gauge is mounted in 1/4 bridge. The full scale output signal is 1.5 mV/V. The conditioning is done via an external electronics. Strain to force conversion is done by calibration on the application. The operating temperature range is -20 to +70°C. The recommended supply voltage is 5 VDC. The application of 2 extensometers mounted in opposition allows to compensate the deflection.
Packaging and acquisition
The strain gage sensor ST500 is supplied with 2,5 to 10 Vdc. Possibility of obtaining a complete and configured measurement chain by adding a display, conditioner or acquisition module:
