VTI measures aircraft tire pressure

VTI Technologies Oy supplies bare die pressure sensors for use in Crane Aerospace & Electronics' SmartStem™ tire pressure monitoring system. The capacitive pressure sensors are built into the tire’s inflation stem that makes the daily tire pressure check quick, easy, accurate, and automatically documented.  This technology is passive, obtaining its operating power from an external reader or interrogator.  The advantage to this system is that there are no batteries, power sources, or wires.  


Maintaining proper tire pressure is very important both to aircraft safety and economics. VTI's measurement philosophy provides an easy and cost effective approach to measuring pressure, especially in extremely harsh environments.  The pressure sensor has enabled SmartStem™ to become a new standard in tire pressure maintenance, thus leading to improved tire wear, reliability, and lower aircraft operating costs.

VTI develops sensors with competitive features for various applications in automotive, medical, sports & wellness as well as in instruments and handheld terminals. The vast experience and robust manufacturing processes have made it possible for VTI to develop products that can be used in systems where low power and good temperature stability are essential. 

"The demand for tire pressure measurement applications is growing. VTI can offer pressure measurement solutions that are based on capacitive measurement principle providing a very low power solution with parallel resistance higher than 10 GOhm. These features are highly appreciated by the aircraft industry.  VTI's pressure platform not only offers good temperature stability but also provides extremely high resolution, particularly for those applications where minor pressure changes need to be measured," says Rick Russell, Director of Sales and Marketing, VTI Technologies.
