Sometimes there can be a bit of confusion as to the difference between a material tester and a force tester. Force testers were designed to make basic force measurements in applications where the primary interest is in peak load and extension. Force testers usually use a force gauge as the load measurement device. However, material testers are much more precise and typically offer a much greater performance level. Material testers will use precision load cells along with an internal or external extensometer for elongation measurement. Testing under consistent loads or using thermal chambers requires a materials tester. Read on to learn the primary differences between material testers and force testers!
The Benefits of Mechanical Force Stands
Mechanical test stands provide you with an economical, manual testing system for compression and tensile testing either in a production environment or within the laboratory. Testers might be equipped with a quick-action lever or a precision hand-wheel to control crosshead travel and speed. Usually, mechanical testers offer a capacity of up to 2500N.
The Applications of Motorized Force Testers
Motorized force testers could be used for tensile, compression, shear, flexural, and peel testing. Motorized test stands can have a much larger work area, which makes them ideal for production environments and applications with larger test samples. Crosshead speed movement is very user-selectable. Digital and mechanical load limits can also be used to control crosshead movements, like stopping the crosshead when a load limit has been achieved.
The Applications of Pneumatic Force Testers
Pneumatically-operated force testers utilize dry, clean, compressed air and are suited for use in hazardous spots where no electricity is allowed for fear of explosion. Pneumatic testers can perform tensile and compressive tests with variable ram speeds. The usual applications include measuring break strength of electrical leads, terminals, wire wraps, connectors, and more.
Material Testers and Their Applications
Material testing machines guarantee the top level of performance and capability for production testing, laboratory testing, quality control, research, and education, with force capacities ranging from around 1 kN to 300 kN. Material testing machines can test for compression, tensile strength, flexure, tear, peel, friction, shear, adhesion, insertion, ductility, shear strength, and many more parameters. They’re used to determine the mechanical and the physical properties of raw materials and components and are ideal for testing of finished goods in laboratories.
