Extensometers for Mechanical Testing to Measure Elongation
Strain Measurement for Materials Testing.
Over thirty years of experience have been invested in the development of our products. At our facilities in Jackson, Wyoming, we design and manufacture extensometers for testing applications worldwide.
.
Extensometers are available for testing nearly all engineering materials, including elastomers, plastics, composites, metals, ceramics, geomaterials (such as rock, concrete, and asphalt), and biomaterials like bone.
.
Models are available for small and delicate specimens—including relatively fine wire—up to large metal samples and substantial rock cores.
The wide range of models covers nearly every type of test, including: tensile, compression, bending, fracture mechanics, and strain-controlled cyclic testing such as low-cycle fatigue.
.
Many of the extensometers are also capable of operating at relatively high frequencies..
General-purpose extensometers for axial tensile, compression, and cyclic testing. Gauge lengths range from 0.5 to 2 inches (10 to 80 mm), with measurement ranges from 5% to 100% strain.
These extensometers are designed to test a wide variety of materials, including metals, plastics, composites, and ceramics.
The dual-flexure design makes them highly durable and insensitive to vibrations, allowing for higher operating frequencies.
The quick-attach kit can be removed, enabling the extensometer to be mounted using springs or elastic bands. Model 3542 extensometers are strain-gated devices, which...
A single integrated unit provides simultaneous lateral (transverse) strain measurement and averaged axial strain measurement. The unit is also available as an averaged axial-only extensometer.

Servohydraulic dynamic fatigue universal testing machines from Sw+b offer a wide range of dynamic and fatigue testing systems in various force capacities and configurations to meet quality control, production, research, and product development requirements.
We provide flexible, reliable, and high-performance testing systems in standard designs or as customized solutions, ranging up to high-force testing for materials and components.
The test specimen is the most critical component in tensile testing, as it determines the true physical properties of the metal or plastic being tested.
The physical test sample must conform to precise dimensions—within thousandths of an inch in every dimension—and must be free from heat- or cold-induced work.
While skilled laboratory personnel and properly calibrated universal testing machines are essential, the final test results ultimately depend on the quality and precision of the specimen...

¿Qué es una Máquina de Medición por Coordenadas? Es un instrumento de metrología de alta precisión que se utiliza para determinar las dimensiones geométricas de una pieza física. Funciona midiendo puntos en la superficie del objeto en los ejes X, Y y Z, creando así un modelo tridimensional exacto que puede compararse con un diseño CAD (Computer-Aided Design).
sirve para: Verificar dimensiones y tolerancias de piezas mecánicas o industriales, Comparar las medidas reales con los modelos CAD para detectar desviaciones, Controlar la calidad en procesos de fabricación de alta precisión, Revisar y calibrar moldes, utillajes y componentes complejos, Generar reportes automáticos de inspección dimensional.
Son esenciales en laboratorios de metrología, industrias automotriz, aeroespacial, médica y de moldes, ya que aseguran que cada pieza cumpla con las especificaciones exactas del diseño antes de su ensamblaje o uso.
