WILCOXON | MARINE APPLICATIONS | HYDROPHONES

Hydrophones are underwater microphones for acoustic measurements. Wilcoxon Sensing Technologies hydrophones are built to withstand the rigors of continuous underwater exposure in both sea water and fresh water environments. Each hydrophone uses piezoelectric crystals with a built-in electronic amplifier, to boost the low level signal of pressure waves underwater signals. The output is a dynamic AC signal superimposed upon the DC Bias Output Voltage (BOV).

Typical applications

  • Underwater biological studies
  • Ship noise studies
  • Pump and machinery studies
  • Monitoring of underwater ordinance
  • H505L
H505L
  • Designed as a small, versatile, self-amplified hydrophone for general purpose applications to a wide variety of underwater acoustic measurements.
  • The internal amplifier eliminates triboelectric cable noise, connector contamination problems and the requirement for an expensive in-line amplifier.
  • The hydrophone and cable entry are completely encapsulated in polyurethane. This alleviates water intrusion caused by cathodic action.
  • Applications for the H505L include underwater biological studies, ship noise studies, pump and machinery studies and monitoring of underwater ordnance.
  • Frequency response +/- 3dB 2 to 10 KHz
  • Maximum temperature 80ºC
  • Maximum operating depth 250 m
  • H601

  • Manufactured in ISO 9001 facility

WILCOXON | MARINE APPLICATIONS | VECTOR SENSORS

Wilcoxon vector sensors measure the acoustic pressure and particle acceleration in three orthogonal axes. These four sensing elements are located in a single housing with a common acoustic phase center. The four channels of the vector sensor, when combined, produce a cardioid directivity pattern which provides approximately 4.8 dB improvement in the signal to noise ratio over a traditional omni-directional pressure sensor. In addition, engineering sensors are embedded within the housing and, when combined with acoustic sensors, can provide a bearing to the target.
