ICP® piezoelectric strain sensor, titanium hsg

This high-resolution dynamic alternative to bond foil strain gauges uses a quartz sensing element in a durable, titanium housing. It has 0.0006 microstrain resolution, 5 volt output, 100k Hz frequency response and 0.5 gram mass for lightweight test articles. The reusable sensor comes with a calibration certificate, attaches to the test specimen in 60 seconds and is removed in 10 seconds.

  • Measurement Range: 100 pk µε
  • Sensitivity: (±20%)50 mV/µε
  • Broadband Resolution: 0.6 nε
