The base is made of highly heat-resistant polyimide and the gauge element is made of NiCr alloy foil, thereby letting the high temperature foil gauges exhibit superior characteristics over a wide temperature range.
The weldable or encapsulated strain 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-gauge elements and insulation material sealed in. The flange is spot-welded to the measuring targets.
