High Frequency Pressure Sensors

ICP® Tourmaline Underwater Blast Sensor

Series 138 Sensors measure shock wave pressures associated with underwater explosion testing. The sensors are structured with a volumetrically sensitive tourmaline crystal, suspended and sealed in an insulating, oil-filled vinyl tube. They have integral microelectronics. These underwater shock wave sensors provide a clean, non-resonant, high-voltage output through long cables in adverse underwater environments. They can be supplied with a sealed cable of appropriate length, ready to operate. Two physical configurations are available.

Highlights:

  • ICP® underwater blast explosion pressure probes
  • Ranges from 1000 to 50k psi (6894 to 344,740 kPa)
  • Rise time < 1.5 µsec
  • Resonant frequency > 1M Hz
