ELWAVE’s ESENSE measures underwater electric fields with sensitivity below 10 pV/m at 1 Hz. Combining a DC–2,000 Hz bandwidth with sampling rates up to 4 kHz, it supports passive detection and electric signature measurement in acoustically noisy environments and adverse acoustic propagation conditions.
Robust titanium dry electrodes and self-calibration support persistent deployment. Available as an OEM solution or an assembled ESENSE 300 system, ESENSE supports up to three-axis electric field measurements. ESENSE 300 features a 300 m-rated aluminium housing, with a 6,000 m titanium version available on request.
Defence and security applications include counter-UxV and underwater intruder detection, anti-submarine warfare, electromagnetic signature intelligence and management, and mine countermeasures. ESENSE also supports offshore applications including cable inspection, contactless pipeline cathodic protection surveys, environmental monitoring and diver safety.
ESENSE 300 is supplied with OWLIA data acquisition and analysis software, providing real-time visualisation and replay, electric field plots and spectrograms, demodulation, digital filtering and CSV export.
