METHOD AND SENSOR ARRANGEMENT FOR TRANSMITTING ENERGY TO A SENSOR

A method for transmitting energy to a sensor comprises transferring energy from a primary side having a primary coil to a secondary side having a secondary coil, wherein the sensor is arranged on the secondary side, wherein transfer of energy occurs via the two coils, wherein the two coils are designed to transmit data bidirectionally; acquiring a measured variable using the sensor; transmitting the measured variable from the secondary side to the primary side; requesting an energy pulse from the primary side when an event occurs that requires more energy; interrupting transmission of the measured variable; transmitting an energy pulse from the primary side to the secondary side; and returning to the normal mode upon acquisition of the measured variable; and transmitting to the primary side the measured variable. Also disclosed is a corresponding sensor arrangement for carrying out the method.
