KHCR Encapsulated Strain Gages
KHCR encapsulated strain gages/gauges 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. The key feature is it enables static/dynamic strain measurement at 25ºC up to 750ºC. To minimize thermally-induced apparent strain, the half bridge is configured with active and dummy gages. The short gage length of 5 mm enables installation to a limited space. It has an applicable linear expansion coefficients (×10-6/℃) of 11,13 and 16.
