Acoustic Target Impact Localization System
ATILS
In peace time, for training purposes, artillery units conduct their frequent target practicing.Both the skills of the gunners and the forward observers need to be improved, their communication cycle to be shortened.Forward observing is a dangerous task during war time, causing a justification to find other ways to localize impacts and adjust fires.Furthermore, the sheer lack of a line of sight, because of topography and/or weather, also thrives the need for other solutions to determine the impact coordinates.

AE Valve Leakage Detector
SVLD1
Through acquisition, processing, and calculation of acoustic emission signal of the valves, SVLD1 could generated root-mean-square voltage (RMS), average signal level (ASL) and power (P) parameters as which could judge the leakage. Meantime, you can pre-calibrate the leakage quantity for the specified valve, and calibration curve of parameters and leakage could be calculated by SVLD1, so as to give the valve leakage reference value during the test.

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.

Directional Microphone
MI-8100
MI-8100 is a shotgun type directional microphone which sharply catches the intended sound. This directional microphone is helpful for the removal of background noise in the simple sound source exploration and in abnormal sound detection. Flat frequency characteristic from 50 Hz to 20 kHz and sharp detection with high S/N ratio provide high sensitive detection of various sound coming from the specific direction. By combining the acoustic vibration monitor BL-1100, only the intended frequency or sound is focused and caught clearer.

Ocean Surveyor
Teledyne Marine RD Instruments
For decades, Teledyne RD Instruments has been the preeminent supplier of Acoustic Doppler Current Profiling (ADCP) instrumentation for open ocean applications. Teledyne RDI’s vessel-mounted Ocean Surveyor family of ADCPs continues to raise the bar, collecting detailed maps of the distribution of water currents and suspended materials through the water column and along the ship’s path - at depths and resolutions previously considered unattainable. In real time, the ADCP is also used to aid in situ decision-making, to adapt field operations, and to understand current regime characteristics.

Portable Fuel Dilution Meter
FDM 6000
The FDM 6000 is a portable, battery operated fuel dilution meter that determines the concentration of fuel dilution present in an oil sample within a matter of minutes. The FDM 6000 uses a unique patent pending fang design to pierce the cap of a disposable sample vial and draws in the headspace from the vial. The headspace flows over a SAW (Surface Acoustic Wave) sensor which reacts specifically to the presence of fuel vapor with a detection range of 0 – 15%. It can detect diesel, gasoline or jet fuel in engine oil. It conforms to ASTM D8004 - "Standard Test Method for Fuel Dilution of In-Service Lubricants Using Surface Acoustic Wave Sensing"
