The invention describes a cost-effective temperature probe which can be used in a flexible manner and has a sleeve (19, 25), a plurality of temperature sensors (T1, ..., Tx) which are arranged above one another in the sleeve (19, 25), are respectively connected, in a parallel manner with respect to one another, to earth (GND) and to a communication line (K) that is routed in the sleeve (19, 25) and are supplied with energy via said line, and a superordinate unit (23) which is connected to the communication line (K), in which each temperature sensor (T1, ..., TN) is used to measure a local temperature in the area surrounding the respective temperature sensor (T1, ..., TN) and to provide the superordinate unit (23) with said temperature in the form of a digital temperature signal using the communication line (K).
