VTI Measures Aircraft Tyre Pressure

Finnish firm, VTI Technologies Oy, will supply bare die pressure sensors for use in Crane Aerospace & Electronics’ SmartStem(TM) tyre pressure monitoring system. The capacitive pressure sensors are built into the tyre’s inflation stem and the technology is passive, obtaining its operating power from an external reader or interrogator. The advantage being that there are no batteries, power sources, or wires.

“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.
