Vector sensors

Vector sensors measure the acoustic pressure and particle acceleration in three orthogonal axes. Four sensing elements, located in a single housing with a common acoustic phase center, combine to 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.

Product Description

Vector sensors measure the acoustic pressure and particle acceleration in three orthogonal axes. Four sensing elements, located in a single housing with a common acoustic phase center, combine to 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.

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.
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).
