TPMS Receivers

The TPMS receiver decodes the radio frequency (RF) signals transmitted by each of the vehicle’s tyre-pressure sensors. The receiver uses its pre-programmed pressure thresholds to alert the driver when a tyre-pressure sensor detects pressure loss. The receiver uses the vehicle’s network to communicate any TPMS or system diagnostic messages. The receiver monitors wheel rotational direction (transmitted by the pressure sensors) and the received signal strength information (RSSI) for each sensor: this enables it to automatically determine the location of each sensor on the vehicle. Because of this, the sensors do not need to be reprogrammed after the tyres are rotated. The display automatically updates with the vehicle’s new tyre and sensor positions.

Applications: Receiver for TPMS-equipped vehicles that can provide Basic TPMS (low tyre light only) or Premium TPMS (auto-learning of replacement sensor IDs and auto-location of the vehicle’s four TPMS sensors after tyre rotation, eliminating the need to reprogram new sensor positions).
