AWCH-2 1-gauge 4-wire System

Hermetically sealed construction with a small size gauge base

About the AWCH-2 1-gauge 4-wire System

This strain gauge features hermetically sealed construction with small sized gauge base. It applies to the measurement in 1-gauge 4-wire method, and the operational temperature is up to 200°C.

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.
