Main purpose
This series of electronic extensometers supplied by Jinan Jinli Testing Instrument Co., Ltd. (Jinan Jinli Testing Machine Factory) adopts the principle of resistance strain gauge and adopts a cantilever beam structure. The elastomer is made of special alloy material and treated with pulsation to eliminate residual stress. Use high-quality strain gauges and connect them as a full bridge. It has many characteristics such as light structure, easy use, stability and reliability. It is an essential sensor for automatic strain testing. This product is mainly used for transverse or radial deformation testing, such as elastic modulus, specified plastic extension strength, specified total extension strength, various elongations, strain hardening index and other parameters.
Radial extensometer
Used to measure and control the radial deformation of specimens in materials testing
Axial extensometer
Used to measure and control tension, compression or fatigue The amount of axial deformation within the gauge length of the specimen during testing.
Main technical parameters
