About the AW-6-350 Quarter Bridge with 3-wire System

This gauge has corrosion-resisting stainless steel base with thickness of 0.08 mm. It is easily installed by using a dedicated spot welder W-50RB. It is suited to strain measurement up to 300°C, measurement of specimen to which adhesion is not applicable, and/or long term 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.
