Difficult conditions measurement unit having sensor mounted moving element and rechargeable energy source recharged using moving/stationary element recharge antennas whilst detector near stationary section.

摘要

The measurement device has a sensor (20) mounted in a moving element (8) relative to a base (14). The moving element can take up several positions one of which is near to the base. The measurement device has a rechargeable energy source (22) equipped with a charging antenna (23-2) coupling to a second charging antenna (23-1). The coupling is only carried out when the mobile element is in the near position to the base.
