PCB® has extensive experience with underwater vibration testing and dynamic pressure measurement caused by unsteady water flow. Our waterproof accelerometers and underwater pressure transducers can be used to measure and identify vibration, cavitation, and dynamic impact pressure from waves.


Key features of PCB underwater sensors

  • Waterproof pressure tested cables can be over-molded directly to the sensor
  • ICP® voltage output or constant voltage line driver (CVLD) current output for electrical noise reduction.
  • Electrical case isolation.
  • Corrosion resistant construction

Our underwater sensor types include:

  • Pressure
  • Vibration
  • Force
  • Underwater Blast
  • Cables

We have an extensive line of off-the-shelf models to meet your requirements. Custom solutions are also available (Learn More).
