General purpose hydrophone H505L

General purpose hydrophone H505L 

Product Description

The H505L hydrophone is designed as a small, versatile, self-amplified hydrophone for use in a wide variety of underwater acoustic measurements. Ruggedness, low cost and an ultra low-noise internal amplifier are prime features of this model. 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, preventing water intrusion caused by cathodic action. The assembly uses preaged piezoelectric (PZT) sensing elements.

Sensitivity tolerance: -160.0 dB re 1V/µPa

Low frequency: 2.0 Hz (120 CPM)

High frequency: 10.0 kHz (600 kCPM)

Maximum temperature: 80°C

Designed to military specifications


  • Rugged design

Wilcoxon underwater accelerometers are designed to be used virtually anywhere under continuous submersion. They are built to withstand the high pressures of deep submergence. Titanium cases are used when the accelerometer must be highly resistant to galvanic corrosion or mounted on titanium structures. Stainless steel can be used for applications where the accelerometer will be mounted on cast iron or mild steel structures since they are near one another on the galvanic series list.
