Tension and compression testing are used to measure how a material reacts to push and pull forces. It’s a common way to determine a material’s mechanical properties, which are important for designing components and assessing their performance.

In the test, a sample is placed between a load cell and a fixed base plate, and a beam moves the sample. The load cell records the force on the sample, and an extensometer measures the strain.

Tension tests are used to calculate the load a material can withstand before tearing or breaking, and the extent of its degradation up to that point. It can be used to measure the strength of a metal or plastic or to assess bonded, welded or riveted joints.

Compression testing measures how a material responds to crushing loads. It involves applying pressure to a material specimen until it reaches a point of instability. The test results in a stress-strain diagram that shows the material’s properties, including elastic limit, proportionality limit, yield point, and compressive strength. Compression testing is important for determining if a material is suitable for a specific application or if it will fail under certain stresses.

The Series 2 digital force gauges from Mark-10 Corp. are designed for basic tension and compression force testing applications up to 500 pounds. Peak tension and compression readings are reliably captured via the gauges’ ±0.5 percent accuracy and 500 hertz sampling rate. Results can be displayed in one of three units of measurement.

A backlit graphic LCD displays the current, peak tension, or peak compression reading. A USB output is provided for data collection.

These compact gauges are overload protected to 200 percent of capacity. An ergonomic, reversible aluminum housing allows for handheld use or fixture mounting. It is rugged enough for applications in both production and laboratory environments. The gauges are compatible with a variety of test stands and grips.
