Encapsulated Strain Gages
Encapsulated strain gages are hermetically sealed. They consist of a sensing part and a cable to transmit output signals from the sensing part. The sensing part is composed of a metal tube and a flange. The highly heat-resistant metal tube has strain-gage elements and insulation material sealed in. The flange is spot-welded to the measuring targets.
Enable dynamic strain measurement at up to 800ºC. The quarter bridge is configured with an active gage and the short gage length of 5 mm enables installation to a limited space.
