Tips: What’s the difference between high temperature strain gauge and ordinary strain gauge?

High-temperature strain gauges and standard strain gauges appear similar in form, but from the sensitive grid material, substrate, adhesive, and leads to stability, they are all redesigned for high-temperature resistance. Standard strain gauges typically employ constantan alloy and polyimide adhesive substrates, with a typical temperature range of -30°C to +80°C. At higher temperatures, substrate softening, resistance drift, and adhesive failure occur, leading to measurement inaccuracies or even damage. High-temperature strain gauges, however, employ high-temperature alloys like Kama, platinum-tungsten, or Invar for the sensing grid. They incorporate heat-resistant adhesive bases, inorganic substrates, or ceramic substrates, paired with specialized high-temperature bonding adhesives and conductors. enabling operation at 200°C, 400°C, or even higher temperatures. They exhibit lower thermal output, reduced creep, and superior thermal stability, ensuring reliable measurements in harsh environments like engines, metallurgy, and high-temperature pipelines without accuracy degradation or structural failure due to heat.
