ALPS begins mass production of batteryless TPMS
Back in May, Japanese company ALPS Electric and German firm IQ-Mobil signed an exclusive worldwide licensing contract, whereby ALPS will develop and produce a batteryless tyre pressure monitoring system. Mass production of such a system is about to start. Batteries, says ALPS, have a finite life, plus there are possible environmental and weight problems. The new batteryless TPMS replaces the central receiver with a transceiver, which transmits and receives signals and a transponder, which replaces the transmitter in the pressure sensor and uses the energy of the signals received to send a return signal.
