Piezoelectric High Pressure Transducers – GP Series

Piezoelectric high pressure transducers based on GaPO4 technology
  • High accuracy
  • High reliability
  • High sensitivity
  • Wide measuring range
  • Small dimensions




Compared with Quartz Gallium Phosphate has significant advantages:
  • Thermal stability up to 970 °C
  • Excellent stability of piezolectric constant over a wide pressure range
  • Twice the sensitivity of tourmaline and quartz
  • No pyroelectricity
  • Stable material due to industrial process
