China North Industries Group 52 Research Institute：Fully automatic extensometer

Device model: AE202

Product use: automatic tracking and measurement of specimen deformation during material tensile test。

Manufacturer: Shenzhen Wanji Test Equipment Co., LTD

Equipment use:

      The automatic extensometer is mainly a device for automatically tracking and measuring the specimen deformation during the material tensile test。The measurement of automatic extensometer is divided into longitudinal measurement part and transverse measurement part. The longitudinal measurement part of automatic extensometer can automatically adjust the scale distance, automatically clamp or loosen the sample, and realize the measurement of the deformation of the sample length direction。The addition of the transverse measuring part of the automatic extensometer can automatically grip and loosen the sample in the width direction, so as to measure the width deformation of the sample。According to the measured values, the elastic modulus, elongation after fracture, plastic strain ratio (r value) and tensile strain hardening index (n value) of metal sheet and thin strip can be obtained。

Main features:

Using imported grating displacement meter, the resolution can reach 0.05μm；

The clamping arm of the measuring part of the automatic extensometer can be automatically clamped or loosened according to the setting of the test, which saves the trouble of manually loading and unloading the extensometer and the resulting error。

The unique design of the fully automatic extensometer structure can track the specimen to fracture without damaging the extensometer;

The mark distance of the longitudinal measurement part of the automatic extensometer is in the range of 20mm-200mm, which can be automatically adjusted according to the software setting.

The special design of the knife edge of the longitudinal measuring clamping arm can meet the needs of the plate and bar samples.

The plastic strain ratio (R-value) of sheet metal and thin strip can be accurately measured by adding the transverse measurement part.
