STN series






Most common type of bondable high-temperature wire strain gages for static and dynamic loads in the temperature range up to +900°C. Sensitive grid of the gage is made of 20…30 um diameter nickel-chromium alloy wire. Sensitive grid is fixed on the temporary backing, possible in two variants: filter paper or fiberglass-reinforced PTFE. Lead wires are made of ribbon or flat wire with 0.07…0.15 mm diameter. Material of the lead wires correlates with the sensitive grid material and also nickel-chromium based.
