AML Smart•X

Perfect for AUV’s, ROV’s,  Gliders and In-Situ Deployments

Smart•X is a real-time instrument that allows you to change the instrument’s sensor load, in-the-field and on-demand. With Smart•X, your SVP can become a CTD; Shallow pressure sensors can be swapped for deep; and temperature range can be extended or tightened, as needed. One single real-time instrument meets multiple deployment requirements.

Field-swappable sensors also streamline recalibration: instead of sending the entire instrument back to a recalibration centre, calibrated sensor-heads can be sent to the instrument. Changing sensors is easy: simply unscrew one sensor-head and replace it with another. Smart•X offers high-speed 25Hz sampling, ensuring excellent data resolution.

Smart•X is ideal for long term, in-situ deployments with UV•Xchange for biofouling control. By eliminating biofouling-induced drift, UV•Xchange allows sensors to perform to their full potential on in-situ instruments. Install UV•Xchange on a Smart•X for a high performance in-situ CTD.

Also ideal for AUV or ROV work, and for sea surface sound velocity measurement for multi-beam systems when equipped with a sound velocity sensor. The instrument is available in 1 or 3 sensor configurations; form factor and functionality vary slightly between the two.

Available Sensor-Heads

X•Series instruments are compatible with our Xchange™ sensor-heads:

Sound Velocity: SV•Xchange™
Conductivity: C•Xchange™
Temperature: T•Xchange™
Pressure: P•Xchange™
Turbidity: Tu•Xchange™
Sensor-heads are ordered separately.
