Stack show groundbreaking TPMS at 2010 Autosport Engineering show

Stack’s Battery-less TPMS systems completely redefines tyre pressure monitoring in motorsport. Based on patented SAW sensor technology, the problems associated with mounting batteries and complicated electronics in sensors on wheels have at last been completely eliminated.

Stack, celebrating its 25th anniversary and a regular exhibitor at Autosport International, will be showcasing its new ground-breaking TPMS products at the NEC show. Developed in-house at its Bicester, UK HQ, the system is already proving popular with teams looking to use fast, accurate analysis of tyre pressure and temperature data to improve both performance and safety.

Dynamic tyre pressure monitoring while out on the track allows the team to optimise tyre performance over a whole lap and the whole race.

"A Tyre Pressure (and Temperature) Monitoring System is a proven performance enhancer! The right tyre pressures deliver consistent performance advantages in all levels of motorsport.“ said Stack’s Managing Director, Alan Rock.

Stack’s battery and wire–less system means unrivalled reliability and significantly reduced running costs with no user maintenance required during full service life. The Stack system is the smallest TPMS sensor on the market - 18mm diameter x 14mm depth (excl. valve stem); 10g weight.

Proven in the harshest environments, the flexible system supports a virtually unlimited number of wheel sets with just one module interrogating 1, 2 or 4 wheels – making it suitable for cars, trucks and bikes. CAN-bus output of pressures and temperatures allows easy integration with existing data-logging systems.

TPMS continues Stack's tradition of leading the way in the innovative use of new technologies and provide our customers with advanced, quality engineered products across Motorsport.
