TPM Sensors



With the passing of the Transportation Recall Enhancement, Accountability, and Documentation Act (TREAD) in November 2000, RTPMS will become compulsory on all cars produced in the USA and compliance to this ruling will be implemented as early as 2003.

Based in Northern Ireland, Schrader Electronics specializes in the design and manufacture of Remote Tire Pressure Monitoring Systems (RTPMS). It is the market and technology leader in the industry. Schrader's business has been steadily increasing since 1996, well before tire pressure monitoring became a prominent issue with the Firestone recalls in the summer of 2000. At present, Schrader's systems can be found on the Citroen C5, Chevrolet Corvette, Cadillac SeVille, Cadillac DeVille, Plymouth Prowler, Renaul Laguna II, and the Peugeot 607 in Europe. The company is also the approved supplier for these systems to Ford Motor Company, General Motors, Daimler Chrysler, Nissan, Renault and PSA in Europe.

Schrader's current Generation II Smart Valve® RTPMS consists of 4 or 5 tire valve mounted pressure transmitters, which send tire pressure information at regular intervals via radio frequency to a central receiver in the car. The receiver is then linked to displays on the dashboard or rear view mirror.

GEN2 features and specifications:

  • Valve mounted transmitters are compatible with traditional assembly plant processes and equipment as well as standard aftermarket tire service equipment.
  • At a weight of 34 grams, it is the lightest TPM sensor in the market
  • Battery powered for long life; 10 years or 150,000 miles.
  • Electronics are sealed and protected from moisture, dirt and survives temperature extremes (-40° C to 125° C).
  • Silicon pressure sensor range 0 - 150 psi.
  • Pressure measurements have 0.2 resolution and ±2% accuracy over operating temperature range. ¨True gauge pressure¨ or ¨temperature referenced¨ formats are available.
  • Tire temperature data available
  • RF communication link offers wireless installation.
  • Transmission frequency of 315 MHz; 433.92 MHz and 868 MHz (Under development) to meet Worldwide RF legislative requirements.
  • Each transmitter has a unique ID code that prevents vehicle ¨crosstalk.¨
  • For ease of installation and service, each transmitter can send a signal on demand.

In its ongoing mission to maintain its market leadership position in design and innovation, Schrader recently announced the introduction of its new third generation (GEN 3) tire pressure sensor. The GEN3 will be by far the most competitively priced sensor on the market with at least a 31 percent improvement in size and weight over any other sensor available today. This next generation sensor exceeds all of the standards set by NHTSA in the newly released performance ruling under the Tread Act.

Carl Wacker, Worldwide Marketing Manager remarked: ¨we are very excited about the Schrader Smart Valve® and our future technologies. The tire pressure monitoring industry is still set for high growth and Schrader Electronics will continue to advance its technology to meet the current and future demands.¨
