AWH-4/AWH-8 Full bridge
The backing material is available in Inconel 600 or SUS304 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 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.
