First appearance of Autonnic, leading Magnetic Sensor Manufacturer, at Oceanology International 2012, 13-15 March London Excel - March 12, 2012

On the surface of the sea, Autonnic Research Ltd has an international reputation for magnetometer-based sensors.  In particular it is the leading maker of sensors for the world’s marine compass and autopilot manufacturers.  Now, for the first time, Autonnic is showing at Oceanology International 2012,  to introduce its range to the underwater world at stand M600K from the 13 -15 of March.

Magnetometers can be used simply to record the ambient magnetic field either as an absolute measurement or, with two or more in a linear arrangement, to record the local variation of field.  In this way very sensitive measurements can be made to locate pipelines or detect the movement of iron-based structures. The A4051 series is currently being used for this.

But when used as orthogonal pairs the fluxgate sensor hass unsurpassed signal-to-noise for angle measurement with high bandwidth. The angle of the Earth’s field is an obvious need for navigation and Autonnic offer pitch and roll compensated solutions so that Heading is resolved in only the horizontal plane; an example of this is the A408X series of digital Compass Sensors.

A particular feature of sub-sea automation is to measure the angle of Vanes or Manipulators and here the ability to sense through pressure housings allows cost-effective and precise sensing for control and monitoring. The A3030 is encapsulated and can be operated at up to 100Bar.
