Model:AWHU-5/AWHU-8
Use:Full Bridge Strain Gauges for Static or Dynamic Measurement
These gauges are usable up to 800°C for both static and dynamic measurement. Although it has a half bridge construction consisting of active and dummy gauges, the measurement is made by the 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.
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.
