It is designed to measure extension mechanically by tracking the separation of two arms, which are clamped to the sample by spring pressure. The EXPlus is designed for use with the LS Series of Lloyd Instruments testing machines. Extensometers are used to accurately measure specimen extension during tensile testing. Specifications for extensometers include gauge length, which is the distance between the knife edges at the start of the test and percent travel or elongation during test.
Designed for measuring r-values in sheet metal testing, this extensometer averages the lateral strain at two locations. This model may be used simultaneously with the Model axial extensometer. Specimen Size: Up to 25 mm width or diameter Measuring Ranges: 2 mm Temperature Range: °C to °C with -LHT option. An extensometer is a device that is used to measure changes in the length of an object. It is useful for stress-strain measurements and tensile tests. Its name comes from "extension-meter". It was invented by Charles Huston who described it in an article in the Journal of the Franklin Institute in Huston later gave the rights to Fairbanks & Ewing, a major manufacturer of . Product Information High Temperature Extensometers for Creep Testing Creep Tensile on Metals 4-Rod-Extensometer Ceramic and metal version Accessories for temperatures up to °C Inserts for different specimen shapes and sizes • Round specimen: Ø 4 mm to Ø 10 mm • Flat specimen: 4 x mm, 6 x mm. EXA Axial-Extensometer Clip-on extensometer EXA,25 for measuring change in length, e.g. on flat and round specimens. Easy to mount clips provide secure seating of specimens with rough and uneven surfaces. lo: 10 mm Measuring path: ± mm Temperature range: °C to + °C > Specification [PDF].
Extensometers Used to measure and locate settlement, heave, displacement and deformation in soil and rock A wide range including borehole rod, magnetic, and tape type extensometers typically used for monitoring excavations, foundations, dams, embankments, tunnels, shafts and . The original extensometer was developed in the s and was a contact extensometer that requires contact with the material being measured to function. The material’s length fluctuated and it would cause the physical reading to appear on the extensometer. Rod Extensometer Single and Double Point The Single Point Rod Extensometer is an inexpensive, simple, rugged, and reliable device to monitor deformation in under ground workings. The Double Point Extensometer incorporates the use of two points which allows the engineer to distinguish between dangerous deep seated movements and more trivial. Dynamic Clip-On Axial Extensometer Series ExA Specially designed for testing new materials, such as carbon fi bres, ce-ramics a.s.o. as well as organic materials. It is characterised by very low weight, high natural frequency, and a high accuracy of ± % of full scale. It allows also dynamic endurance strengthFile Size: KB.
