AWC-8B 1-gauge 4-wire System for Harsh Environments

8mm gauge suited to strain measurement for long term and/or in harsh environment

About the AWC-8B 1-gauge 4-wire System for Harsh Environments

AW series high temperature weldable strain gauge
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.

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.
