About the Extensometers
The 2630-100 series extensometers
convert the mechanical displacement of a
strained test specimen into an electrical
signal. When used with the current range
of Instron testing machines, each
extensometer is automatically recognised,
and can be calibrated at the touch of a
button.
The displacement is transmitted by a light
rigid frame to strain gauges bonded to a
flexural element. The gauges are arranged
in a fully active four-arm Wheatstone
Bridge circuit.
The 2630-100 series of extensometers
includes different gauge lengths/strain
range options to suit a wide range of
specimen characteristics.
