1.Product presentation
This YYU series of electronic extensometer are resistance strain extensometer, which are used to measure the line deformation between two points of a sample or a component under stress.When the extensometer is stretched, it causes deformation of the elastomer and changes the resistance value of the strain gauge pasted on it. The original balance bridge is out of balance and output a voltage signal which is proportional to the deformation, which is then amplified, converted and processed by the computer.
