X-ray Fluorescence Sulfur/Chlorine-in-oil Analyzer
MESA-7220V2
-
The MESA-7220V2 measures both sulfur and chlorine in petroleum based products using the Monochromatic Energy Dispersive X-ray Fluorescence (EDXRF) method. A monochromatic X-ray source is used in order to obtain an ultra-low noise background which affords the best detection limits for both sulfur and chlorine.The detector window size was increased to collect more fluorescent X-rays and thus achieve lower level ppm values. This provides excellent, repeatable performance at both low and high concentrations of both elements.By adjusting the angle of the graphite crystal, the excitation beam can be measured to excite sulfur in the sample, increasing sensitivity.

Mobile Sound Ranging Array
MSRA
-
In a peer to peer conflict, weapon location radars used for counter battery purposes will be extremely vulnerable.With aerial/satellite based surveillance available for the opponent, radars will be seen. With electronic warfare means being omnipresent, radars will be triangulated and jammed. There is an urgent need for 24/7 persistent surveillance with (preferably) passive sensors. With mobility being the key for survival on the battlefield, rapid re-deployable, or even truly mobile sensor capabilities are required. Therefore, the traditional sheer sound pressure based sound ranging capability becomes obsolete, as the triangular footprint of the sensor nodes is too large to be installed on a manned, or unmanned platform. With the trend towards longer ranges and “shoot and scoot” drills, the concept of capturing the muzzle blast noise becomes questionable, as the speed of sound is too slow to provide timely localizations.

Directional Acoustic Transponder (DAT)
-
The Benthos Directional Acoustic Transponder (DAT) is anextension to the Teledyne Benthos ATM-900 Series modem, which automatically estimates the azimuthal and vertical arrival angles of a message sent by a remote modem. The system is a modified ultra-short baseline (USBL) which uses a broadband component of a typical modem message to form estimates of arrival angle(s). While conventional USBL devices employ tonal signals, our appropriate processing of wide band signals provides far better combined range and arrival angle estimation, especially at low Signal to Noise Ratio (SNR). Our device offers a clear 360 degree field of view in azimuth, and an approximate vertical coverage spanning + 90º overhead to -50º below horizontal.
