Description:
TPMS sensor is quick to provide underinflation, leaking, hazardoushi-pressure or hi-temperature warnings, and has consistent waTPMS is a warning system to monitor tire pressure and indicateto the driver when
a tire is significantly underinflated so as to prevent unsafeconditions. It directly
measures tire pressure with an imbedded electronic device, apressure sensor
powered by Li/SOCl2, sending signals via RF transmitter to theindicator in driver''s
cabin.
System Components
The TPM system consists of the following major components
1. 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 vessel
2. 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, andindicator can be customized made.
Key benefits:
-- Compensates for battery conditions and alarm when battery isused up
-- Supports vehicle platforms ranging from 4 tires small cars to 8tires trucks and
across tire technologies
-- Monitors individual tires, detecting changes in pressure andperformance
-- Offers the possibility to couple with a remote keyless entrysystem for a low-cost
total solution
-- Offers the small size and enhanced media protection of the SSOPpackage
