Vehicle tyre air pressure measurement arrangement - contains measurement piston in non-magnetic measurement tube with e.g. inductive sensor

摘要

The method measures the air press. in vehicle tyres and detects critical temp. using a non-magnetic or non-metallic measurement tube (1) with a press. measurement piston (4) and two closure stops (2,3) of weakly magnetic material arranged radially on the wheel rim or inside the tyre. The position of the piston w.r.t. the two stops or w.r.t. an inductive transducer is determined for each rotation of the wheel. USE/ADVANTAGE - For tubed and tubeless tyres. Accurate tyre press. measurement.
