AWM-8 Series Static and Dynamic Quarter Bridge with 3-wire System Straingauges

For both static and dynamic measurement

About the AWM-8 Series Static and Dynamic Quarter Bridge

The AWM is usable up to 300°C for both static and dynamic strain measurement. The backing material is available in Inconel 600 or SUS304 which should be selected according to the test specimen material.

AW series high temperature weldable strain gauge
These strain gauges have strain sensing elements fully encapsulated in corrosion-resisting metal tubes made of stainless steel or Inconel (except AW-6-350). The strain gauge backings are also made of the same material, and the gauges are installed by spot welding to metal specimens using a dedicated spot welder. The maximum operating temperatue is 800°C for the AWHU. These gauges are suited to measurement in high temperature harsh environments such as underwater or gas-filled atmosphere, or for long term. The AWC-2B and AWCH-2 are available in 1-Gauge 4-Wire configuration.
