AWMD-5, AWMD-8 (for dynamic measurement only : -196 to +800°C) Full bridge

The AWMD is applicable up to 800°C and is dedicated to dynamic 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 strainmeter 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.

AWH-4/AWH-8 Full bridge

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 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 Full bridge

These gauges are usable up to 800°C for both static and dynamic measurement. 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 gauge base, junction part and cable of this gauge are constructed small as the standard specifications, and it is suited to the installation on a narrow or curved part.

AWC-2B 1-Gauge 4-wire system (G.F. 2.1 approx.)
AWC-8B Quarter bridge with 3-wire method (G.F. 2.1 approx.)

These strain gauges have hermetically sealed construction with the sensing element encapsulated in the stainless steel tube. This construction helps to simplify the coatings for moisture and water proofing, and the strain gauges are suited to strain measurement for long term and/or in harsh environment. The AWC-2B applies to measurement in 1-gauge 4-wire method.
