, TPMS PIONEER
Spread of TPMS
Legislation on TPMS is being drafted worldwide. In order to improve safety,
US law already requires a tyre pressure control system on all
vehicles since 2007.
In Europe, further motivated by the concern to reduce CO
2
emissions,
a law has been passed requiring tyre pressure control.
The early days of TPMS
In the early 1990s, Schrader developed the first generation of tyre pressure
and temperature measuring sensors.
In 1993, Schrader filed the first TPMS patent. Other patents, like the
"snap-in" valve one, have followed. In 1999, the Peugeot
®
607 was the first
mass produced car in Europe to be 100% equipped with TPMS, followed by
the Renault
®
Laguna.
The system's benefits
Through continuous control of the pressure, the system:
• Prevents tyre bursts due to under-inflation.
• Improves passenger safety by reducing the risk of accident.
• Reduces fuel consumption and increases tyre lifetime.
• Prevents slow punctures.
Energy saving = reduction of CO
2
emissions = Financial saving.
Schrader
®
, leader in TPMS
Schrader's direct TPMS technology is used in over half the automobile
production plants in the world.
In 2012, Schrader passed the threshold of 200 million sensors manufactured.
Schrader's latest innovation is the EZ-Sensor
TM
: first real programmable
TPMS to be patented, designed to replace 90% of the TPMS sensors
integrated in US, European and Asian cars. "EZ-Sensor™" simplifies
the TPMS replacement process on the spares market by considerably
reducing stock levels and reducing the maintenance costs of vehicles
equipped with TPMS.
• 13 July 2009: the European Parliament in Strasbourg officially adopted regulation 661/2009,
which fixed requirements for equipping vehicles with TPMS (Tyre Pressure Monitoring System).
• Effective date: 1 November 2012.
• Vehicles affected: category M1 (passenger cars, 9 seats max, less than 3.5 t).
• Any new car approved after 1 November 2012 must be equipped with TPMS.
• Any new car registered after 1 November 2014 must be equipped with TPMS.
