Bartington Instruments - High-Performance Magnetometers for Marine Defence Applications

Bartington Instruments is a world leader in the design and manufacture of high precision, low noise fluxgate magnetometers and magnetic susceptibility instrumentation for naval defence applications.

Our magnetometers, magnetic gradiometers and data acquisition units are widely used in magnetic signature and degaussing ranges, in surveillance and for magnetic anomaly detection. Our products have a reputation for performance, reliability and durability, and are used globally by many naval armed forces.

Range of three-axis magnetic field sensors

The three-axis magnetic field sensors (Mag-03) is a versatile range of sensors for measurement of geomagnetic and other background fields has applications in analysing the magnetic field signature of ships for degaussing ranges. Sensors are available with a low noise level of <6pTrms/vHz at 1Hz and a bandwidth of 3kHz.

Submersible magnetometer for degaussing ranges

A submersible three-axis magnetometer with high reliability and low maintenance requirements, the Mag-03RC was specifically designed for the measurement of magnetic signatures in degaussing ranges. It can also be used for marine surveillance. The sensor is capable of operation at a depth of up to 2,000m with cables up to 2km in length (above 1km requires an external power supply). It has an inbuilt self-test facility and comes with a low noise specification of <20pTrms/vHz at 1Hz.

Low-power magnetometer

These compact three-axis magnetic field sensors (Mag648S/Mag649S), submersible to 2,000m, have been designed for applications that require very low power consumption (15mW). As such they are suited for battery-operated systems.

Applications include large networks of sensors in harbours, offshore surveillance and intruder detection. The sensors have a noise level of <10pTrms/vHz at 1Hz and bandwidth up to 1kHz.

Data acquisition system

The data acquisition system (DAS1) is a versatile, multi-sensor data acquisition unit intended for use with large arrays of sensors and can take up to 480 analogue inputs. It is designed for operation with most Bartington Instruments magnetometers and is compatible with most other third-party depth and acoustic sensors.

Measurements are sampled, recorded and processed within a self-contained unit. A powerful built-in PC for running data analysis software runs via a LabView based interface.

Submersible three-axis fluxgate sensor array

This array of eight miniature submersible three-axis fluxgate sensors (Mag613) provides measurements over 24 channels (8x3-axis) for precise mapping of magnetic fields. The complete assembly can provide magnetic signature characterisation in pressurised environments up to 50 bars, or 500m depth. Each sensor element is less than 1cm3 and all are connected by a 3m cable to the electronics unit, which contains the power supply, driving circuitry and analogue multiplexer.

Three-axis submersible gradiometer

This submersible gradiometer (Grad-03M) is ideal for detecting unexploded ordnance or pipes and cables on the seabed. Housed within a carbon fibre pressure enclosure, it will operate to depths of 5,000m, and can be mounted on remotely operated vehicles or used on its own. It is available with baseline options of 500, 750 or 1,000mm between sensing elements, which have a noise level below 20pTrms/vHz at 1Hz and bandwidth to 2kHz.
