Schrader Sensor Overview
The Schrader Electronics TPMS (Tire Pressure Monitoring) Sensor is designed to
be used in a direct measurement TPM System. The TPM Sensor is intended to
interface to a receiver/decoder that has been designed to accept the TPM
sensor protocol.
The TPM Sensor is designed to monitor a vehicle's tyre pressure whilst driving or
stationary. An electronic unit inside each tyre (referred to as the TPM Sensor
or TPM transmitter) mounted to the valve stem, periodically measures actual
tyre pressure/temperature.
This pressure information is transmitted to a receiver/decoder by means of an
RF link. The incoming radio frequency signals are decoded, and the data
used to inform the driver of the tyre pressure information via the vehicles TPM
interface.
TPM Sensor main functions are:
• Regularly measure the tyre pressure.
• Monitor if the wheel is moving.
• Periodically transmit tyre pressure using an RF link and a specific protocol.
• Notify the system if there are abnormal pressure variations (leak) in the tyre.
• Monitor the transponder input for valid LF field
