tensofmeter

The tensofmeter is a mechanical testing instrument designed to measure tensile force, elongation, and derived properties of materials under axial loading. It is a variant or specialization of the broader family of tensometers and is commonly used in laboratories and in-field testing environments to assess the tensile behavior of fibers, polymers, metals, composites, and textiles.

A typical tensofmeter consists of a rigid frame with grips to hold a test specimen, a drive system to apply controlled extension, and sensing elements such as a load cell and a displacement sensor. The load cell measures the axial force, while the displacement sensor records the change in specimen length. A data acquisition system logs force and elongation data for real-time monitoring and post-test analysis. Portable versions may integrate a compact display and a microcontroller or computer interface for on-site testing.

Operation usually involves mounting the specimen between grips, selecting a loading rate, and initiating the test. The instrument records force and elongation as the specimen is strained, enabling calculations of tensile stress, strain, and, with cross-sectional area information, properties such as yield strength, ultimate tensile strength, and Young’s modulus. Some tensofmeters also provide control modes for static, monotonic tests or dynamic and cyclic loading.

Calibration and accuracy depend on sensor quality, proper alignment, and temperature stabilization. Common limitations include drift in the load cell and displacement sensor, friction at grips, and the need for correct specimen preparation and measurement of gauge length.
