About the AWMD-8 Full Bridge for Dynamic Measurement

The AWMD is applicable up to 800°C and is dedicated to dynamic strain measurement. A high pass filter is a standard accessory. Using the high pass filter, unnecessary direct current component and low frequency component (thermal output, drift, etc.) are cancelled. A DC exciting dynamic strain meter such as DC-96A/DC-97A, smart strain recorder such as DC-204R, or multi-recorder TMR-200 series should be used for the 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.
