Measuring device, including at least a sensor, capable of operating in difficult conditions

摘要

This invention relates to a measurement device comprising at least one sensor ( 20 ) designed to be installed on a mobile element ( 8 ) free to move with respect to a base ( 14 ), the mobile element being capable of moving into several positions with respect to the base ( 14 ) including a so-called proximity position in which it is close to the base ( 14 ). The sensor ( 20 ) cooperates with a power supply device comprising a rechargeable energy source ( 22 ) equipped with at least one first charging antenna ( 23 - 1 ) located on the mobile element ( 8 ) and at least one second charging antenna ( 23 - 2 ) located on the base ( 14 ), to be coupled to the first charging antenna ( 23 - 1 ) to recharge the energy source ( 22 ). Coupling between the two charging antennas ( 23 - 1, 23 - 2 ) is only made when the mobile element ( 8 ) is in the proximity position.
