Mechanical path meter

FIELD: measurement. SUBSTANCE: invention relates to the field of devices for measuring the distance travelled by a land-based wheeled vehicle, in particular, to mechanical track gauges, and can be applied in odometer systems of land navigation. Mechanical path meter differs from analogs in a tire pressure sensor, the output signal of which is transmitted via a radio channel to the signal receiving and conversion unit. Due to this, when a multi-axle vehicle is moving across the terrain, account is taken of the measurement error of the distance travelled due to various tire pressures of the vehicle. EFFECT: technical result is an increase in the measurement accuracy of the path travelled by a land-based vehicle due to the elimination of an error caused by a change in the rolling radius of the wheel due to a change in air pressure in the tire. 1 cl, 1 dwg
