Acoustic and magnetic ranges

Acoustic Range Sensor

The Underwater Noise Range consists of a number of fixed sea bed hydro phones arranged to detect the sounds radiated from a passing surface ship or submarine. The unit is powered by a single DC power supply, measures and digitises the local water pressure & acoustic signals

Magnetic Range Sensor

The multi influential Magnetic sensor is capable of measuring magnetic fields up to ±70 μT. In addition there are hydro phonea and pressure/depth sensors also integrated in the unit. The unit also has a bi-axial inclinometer to measure the roll and pitch of the sensor
