A sender (1) for transmitting data, in particular the temperature, from an animal body, can be introduced into the animal body. An exciting coil (14) in a sender (13) excites a sender oscillating circuit (12) which, in addition to the sender coil (2), has at least one sender capacitor (5). The sender capacitor (5) contains barium titanate as the dielectric and is therefore temperature dependent. The sender capacitor (5) constitutes a temperature sensor which influences the frequence of the sender oscillating circuit (12). This frequency is measured and evaluated by a receiver oscillating circuit (18) in the receiver (13).
