High Temperature Weldable Strain Gauge

AW series High temperature Weldable strain gauge

These strain gauges have strain sensing elements fully encapsulated in corrosion-resisting metal tubes (except for AW-6). They are suited to use in various environment including in liquids or gases. Installation is easily done using dedicated spot welder W-50R/W-50RB

AWMD-5, AWMD-8 (for dynamic measurement only : -196 to +800℃) Full bridgeCE_logo

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 bridgeCE_logo

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.
