Tyre Pressure Receiver

Formula One SECU version

The tyre pressure receiver unit is for use with MESL high baud rate tyre pressure sensors. The sensors transmit pressure, temperatures, battery voltage, serial number and life count data over an RF link to an antenna on the car. Signals from the antenna are passed to the tyre pressure receiver unit where they are decoded and sent to the ECU via CAN to be further processed and scaled.

This variant is for use with the FIA single ECU. The calibration data for the sensors will be stored in the ECU allowing the package of the receiver to be greatly reduced.
