STP series







Platinum-tungsten based wire strain gages demonstrate perfect performance under dynamic loads in the temperture range up to +1150°C. Sensitive grid of these gage is made of 20…30 um diameter platinum-tungsten 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 is also platinum-tungsten based.
