High Frequency Pressure Sensors

Tourmaline Pressure Bar

This unique non-resonant sensor is designed for instantaneous, reflected (face-on) shock wave pressure measurements in dry environments. A shock wave pressure impacting the very thin tourmaline crystal which operates into a silver alloyed “pressure bar”, eliminates sensor structure response. The sensor has a 0.2-microsecond rise time. The sensor diaphragm end is coated with a conductive silver epoxy.


  • Designed for reflected shock wave pressure measurement
  • Unique non-resonating design, Tourmaline sensing element
  • Pressure ranges from 1000 to 20k psi (6894 to 137,900 kPa)
  • Rise time < 0.2 µsec
