Driver over measurement pads

          Driver over measurement pads

The SilentSensors TPMS is simple, but highly cost effective, alternative to existing TPMS products. The system comprises; pressure sensors, a vehicle mounted reader, plus an optional cab display. Installation and maintenance is simple and straightforward and special tools or "training" when fitting, replacing, or rotating tires, as the system detects individual wheels. The low cost battery-less sensors are inherently simple, being compact and rugged and requiring no maintenance. They can be supplied for OEM applications, where they can be built into the valve of each tire, or for after-market applications, where they can be supplied as either a patch inside the tire, or retrofitted to the stem as a valve extension. Temperature measuring can be provided as an optional sensor upgrade.

A single, vehicle powered, reader module, mounted in the centre of the vehicle, contains the active electronics; this connects to antennas assemblies, running to each wheel arch (paired wheels have a single antenna). The reader repeatedly requests data from each of the sensors in each wheel assembly in turn and sends this data to the cab for display (or to a telematics system for remote monitoring). J1939 (CAN) or wireless options can be supported.

In-cab displays can be provided or the showing tire pressures and/or warning the driver; remote telematics options can be provided.

Features:

  • Very Low System Cost
  • Continuous pressure readout for each tire
  • Sensor can mounted in or on the; wheel, valve stem, or tire
  • Sensors are light and rugged (17g}
  • Accurate pressure readout with average error of +/-1.5 psi at operating pressures
  • No batteries in tire sensors - no maintenance, battery life or disposal issues
  • No wheel position training (coded sensor pairs support for inner and outer wheels combinations), or re-training after wheel rotations. 
  • Each sensor has a unique ID which is be used to record the tire history
  • Pressure and tire ID can be read using a drive-over reader at up to 40mph
  • Pressure and tire ID can be read with hand-held reader

The in-car TPMS product is a product to monitor tire pressure from within motor vehicles. It has been designed to meet both European and US legislation, returning a warning when the pressure falls by 25% of the nominal pressure of the tires. The tire sensors are installed in a patch on the inside of each tire or in stem of tire valve.

Features:

  • Very Low system cost
  • Continuous pressure readout
  • Accurate pressure readout with average error of +-1psi at operating pressures
  • No batteries  
  • No wheel position training
  • Pressure and tire ID can be read with drive-over reader at 40mph (fleet management)
  • Pressure and tire ID can be read with hand-held reader
  • Sufficient accuracy to improve MPG and tire wear
