TPMS Sensor

TPMS sensor is quick to provide underinflation, leaking, hazardous hi-pressure or hi-temperature warnings, and has consistent wa

TPMS is a warning system to monitor tire pressure and indicate to the driver whena tire is significantly underinflated so as to prevent unsafe conditions. It directlymeasures tire pressure with an imbedded electronic device, a pressure sensorpowered by Li/SOCl2, sending signals via RF transmitter to the indicator in driver'scabin.System Components The TPM system consists of the following major components1. Remote Tire Pressure Monitoring (RTPM)-- SOC detecting pressure, temperature, acceleration, voltage, signal process ASIC-- MCU 4-8 bits: ARM7 LPC2292-- RF transmitter: GE NPXII Sensor Chips-- Power management: Li/SOCl2 battery-- Antenna-- Pressure vessel2. LCD Indicator (Information centre)Features:-- Case material: Hi-strength ABS-- Environment: -40oC∼+125oC-- RF: 433MHz -- RF receiver: 4 or 8 tires pressure monitoring-- Battery life: 2 years or 100,000 miles-- LCD Indicator: integrated with automobile information center-- Outside dimensions of TPM sensor, it is sensing range, and indicator can be customized made.Key benefits:-- Compensates for battery conditions and alarm when battery is used up -- Supports vehicle platforms ranging from 4 tires small cars to 8 tires trucks andacross tire technologies -- Monitors individual tires, detecting changes in pressure and performance -- Offers the possibility to couple with a remote keyless entry system for a low-costtotal solution -- Offers the small size and enhanced media protection of the SSOP package
