LX Laser Extensometers are highly accurate, non-contact extensometers. They are ideal for fragile specimens, those susceptible to localized damage, and also specimens that release large amounts of stored energy during breaks. They will meet all the strain measuring needs of materials like plastics, rubber, films, fibers, textiles, and specimens not suited for contacting extensometry.
The family of LX Laser Extensometers are highly accurate, non-contact extensometers. They are ideal for fragile specimens, those susceptible to localized damage, and also specimens that release large amounts of stored energy during breaks. They will meet all the strain measuring needs of materials like plastics, rubber, films, fibers, textiles, and specimens not suited for contacting extensometry. They use state of the art scanning technologies yet are very user-friendly to operate. And they can often out perform comparable video products.
The LX measures extension or strain by scanning the specimen and detecting the location of reflective tape markings. As the marks move during the test, the laser tracks and records their exact position.
Selectable averaging of 2 to 512 scans
Measures the initial gage length of the specimen directly
Can measure strain simultaneously over three segments within the specimen’s gage length
Meets ASTM B1 extensometer classification (25 mm/1 in and longer gage length)
Measurements are updated 100 times per second.
Analog output port for closed loop strain control or for input to a data acquisition board, chart recorder, and so forth
Parallel beam design accommodates operation through chamber glass, a clear bath, water, and so forth
Certified for compliance with the Center for Devices and Radiological Health as a Class II product
