Aviation & Transportation

Aviation

The driving force to move toward high-energy density storage capability of lithium-ion batteries in the aviation industry is evident – weight is paramount when you are in the air. But, so is safety. The Radio Technical Commission for Aeronautics (RTCA) is actively revising their recommendations to improve the safety of rechargeable lithium-ion battery systems that are permanently installed on aircraft. The RTCA standard defines three distinct venting categories pertaining to how off-gas emissions are vented within the battery system design and requires manufacturers to declare the venting category for their battery.

In the Nexceris Sensors division, Li-ion Tamer® systems can be used to provide monitoring of all venting categories outlined in the RTCA standards. Doing so can improve the situational awareness of your system, while providing valuable warning of a failing battery.

Marine

Marine battery safety requirements are developing quickly as adoption of battery systems is beginning to grow. The current regulations are a mix of prescriptive and risk-based rules and include scope concerning off-gassing of batteries. One of our sensor systems can be used to mitigate risks associated with off-gassing of cells.

In the Nexceris Sensors division, Li-ion Tamer® for lithium-ion battery systems can be used to provide monitoring of all venting categories outlined in RTCA standards. The NTM Sensors hydrogen monitors would be a good fit for the lead-acid batteries. Doing so can improve your situational awareness of the system, while providing valuable warning of a failing battery.

Diesel Powered Vehicles

Strict limits are being placed on nitrogen oxide emissions as emission laws and regulations are becoming increasingly stringent. These requirements are creating a worldwide need for better NOx sensor products for both transportation and industrial markets. To meet this demand, Nexceris has developed a new NOx sensing technology that rapidly and selectively measures NOx in combustion exhaust streams. This technology enables accurate quantification of NOx emissions at low concentrations (< 10 ppm) with response time less than 200 milliseconds – a capability that is particularly enabling for improved closed-loop emissions monitoring in diesel engine exhaust systems. Additionally, our sensor technology offers the potential for dual sensing of NOx and NH3 in a single sensor device, which would be an important capability for silicon controlled rectifier (SCR) after-treatment systems.

Fuel Cell Vehicles and Filling Stations

Fuel cells are used in a rapidly growing number of primary and back-up power applications, including forklift trucks, cars, buses, homes and businesses. Detection of hydrogen leaks is essential to the safe implementation of these systems.

Nexceris has developed hydrogen sensors, which are commercially available through its NTM Sensors brand. Integration of our NTM Sense H2®hydrogen sensor in fuel cell systems provides real-time monitoring and rapid detection capability of potential hydrogen leaks before flammable levels are reached. Moreover, installation of the NTM Hydrogen alarm system can provide safety monitoring at hydrogen filling stations or near hydrogen storage containers.
