Extensiometer- Engineering Lab Training Systems.
It Is called 15 cm extensiometer. I! is made of gun metal
and comprises of an accurate hinged ring with stainless steel set screws
held rightly by a spring. The extension is on a dial gauge. I! Is
suitable for 15 cm x 30 cm cylindrical test moulds.
I! has a
control bar fixed on both ends of the extension rod with screws. When
the test specimen has been held by the stainless set screws the control
bar is released and the instrument Is in operation. The extension is
read, while the test specimen is under compression test, on the dial
gauge, which' is fixed to the extensometer. The dial indicator
which reads to 0.0005" or .01 mm gauge shows the average extension on
the sides of the specimen.
