AWH-8 Full Bridge for Static or Dynamic Measurement

Half bridge gauge construction with a full bridge measurement method

About the AWH-8 Full Bridge for Static or Dynamic Measurement

The backing material is available in Inconel 600 or SUS321 which should be selected according to the test specimen material. Although it has half bridge construction consisting of active and dummy gauges, the measurement is made by the full bridge method using the supplied temperature compensation circuit board. The maximum operational temperature is 600°C for static measurement and 650°C for dynamic measurement.

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.
