胎压监测系统（TPMS)

Tire Pressure Monitoring System(TPMS) The Indirect Intelligent TPMS system makes use of the wheel speed sensor signal of ABS system of original vehicle, by comparing the wheel speed differences, and according to the relation between the effective tyre radius and change of wheel speed to detect the tyre pressure indirectly. The system will be self-calibrated after installation and memory the standard pressure of each tyre., and then keep on real-time monitoring of the change of tyre pressure during driving. When tyre leakage exceed setting value, TPMS will automatic alarm to warning the driver to prevent accident and gasoline consumption increase due to tyre leakage. Technical Parameters: Voltage: DC 9 16V Power: <1 W Working temperature: -40°C +85°C Calibration time: 4 18 min Calibration speed: 50 80km/h Alarm response time: 1 5 min Low pressure alarm: 0.8kg/cm2±0.1 kg/cm2 Serious leakage alarm: 1.5 kg/cm2±0.1 kg/cm2
