Wireless 4-Channel Tire Pressure Measurement System with CAN Bus Output

PETRA is a compact wireless measurement system for recording tire pressure during vehicle testing and development. The transmitters replace the standard tire valve caps and transmit pressure data wirelessly to the central receiver.

The system supports up to four tire pressure transmitters and is designed for fast installation without additional wiring to the wheels. Measurement data can be transmitted via CAN bus or USB and configured using the supplied PC software.
