KHC
Encapsulated Strain Gages

  • CE

Summary

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.

Features

Enable static strain measurement at up to 500ºC and dynamic strain measurement at up to 550ºC. To minimize thermally-induced apparent strain, the half bridge is configured with active and dummy gages. Enclosure is made of Inconel 600 or SUS 321.
