AWMD-5, AWMD-8 (for dynamic measurement only : -196 to +800°C) Full bridge
The AWMD is applicable up to 800°C and it is dedicated to dynamic strain measurement. A high pass filter is a standard accessory. Using the high pass filter, unnecessary direct current component or low frequency component (thermal output, drift etc.) in the measurement signal can be neglected. The DC exciting dynamic strainmeter (DC-96A/DC-97A) or the smart strain recorder (DC-204R), Multi-Recorder TMR-200 should be used for measurement.

AWH-8 Fulll bridge
The backing material is available in Inconel 600 or SUS321 which should be selected according to the test specimen material. Although it has a 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.

AWHU-5, AWHU-8 Fulll bridge
These gauges are usable up to 800°C for both static and dynamic measurement. Although it has a 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 gauge base, junction part and cable of this gauge are constructed small as a standard specification and it is suited for being mounted on a narrow or a curved part.
