Electronic Test Equipment
1. introduction
The universal testing machine (UTM), also known as a universal
tester, materials testing machine, materials test frame or
tensometer, is used to test the tensile strength and compressive
strength of materials. It can perform many standard tensile and
compression tests on materials, components and structures, in other
words, that it is versatile.
2. features
This universal testing machine adopts two strong supports, precise
load cell to measure the load. Its crosshead can move up or down at
a constant speed.
This universal testing machine can program the crosshead speed or
conduct cyclical testing, allow testing at a constant force,
testing at constant deformation, testing at constant displacement,
etc.
This testing machine can equip with extensometers to measure the
extension or deformation.
According to test requirement for temperature, humidity, pressure,
etc, special device, such as environmental chamber can be placed
around the test specimen to do test in certain temperature,
humidity or pressure.
Matched with various test fixture, like peal, puncture, tear,
pneumatic grip, belt tension, etc. This UTM can be used to metal,
non-metal, composite materials like rubber, steel wire, plastic,
seat belt, textile character test.
Protecting functions of over load, over current, over voltage,
crosshead limit moving space protection, auto stop at break.
3. software introduction
The measurement and control system is designed purposely for microcomputer controlled electronic universal testing machine, microcomputer controlled
universal hydraulic testing machine and microcomputer controlled compress testing machine, used for tension, compress, bend, shear, tearing andpeel test. With the personal computer and interface plate, it could collect,
save, process and print test result. Further it can calculate multiple parameters, i.e. maximum
force, yield strength, average peel force maximum deformation,
yielding point and elastic modulus; this system is featured in curve process, multi-sensor support, image interface, flexible data process and powerful system function.
