The invention relates to a temperature measuring probe comprising a hollow temperature measuring lance, and at least one temperature sensor which is configured as a resonator and arranged in the temperature measuring lance, and which is/are connected to a communications unit for the wireless transmission of the temperature information. The object of the invention is to develop a temperature measuring probe which permits a design that is variable, is not influenced by an impedance adjustment, and fulfils the respective requirements of the user, and which itself guarantees a long service life with a high level of reliability, i.e. without changes to the temperature characteristic curve, under extreme operating conditions, as well as simultaneously guaranteeing a cost-effective, fully automatic manufacturing alongside an impedance adjustment that is simple from a manufacturing point of view. The temperature measuring probe according to the invention is characterised in that, inter alia, a plate-shaped sensor carrier (10) made of an electrically insulating plastic is arranged in the temperature measuring probe (1), and in that ground conductor surfaces (13) are arranged on both sides on the opposing surfaces (11) of said sensor carrier (10), which ground conductor surfaces function as a ground conductor (7) as a whole and are connected to one another via through-contacts (12) such that they are electrically conductive between one another, wherein free surfaces (14) are arranged in these ground conductor surfaces (13) on one or both sides of the sensor carrier (10), and in that signal conductor paths (15) are arranged in the centre of these free surfaces (14) at an electrically insulating distance from the ground conductor surfaces (13), wherein same are electrically conductively connected to one another via through-contacts (12), provided they are arranged on both sides on the opposing surfaces (11) of the sensor carrier (10), thereby forming the signal conductor (9) as a whole. |
