The aim of the invention is to provide an improved measuring probe which can be used as a high-temperature measuring probe for measuring temperatures continuously for a period of time or long-term. This is achieved in that at least the free inner chamber of the inner protective tube (5) is filled, preferably totally filled, with an inert gas.
The invention relates to a method for determining the reference junction temperature (T2) of a thermocouple (E1, E2). According to the invention, a reference temperature (T3) in a housing (G) is used to determine the reference junction temperature (T2), and also a temperature difference (T2-T3) between the reference junction temperature (T2) and the reference temperature (T3) is determined.
The invention relates to a method for checking a thermometer (TH), which thermometer has a housing base part (B), wherein a measuring insert (ME) for determining the temperature is inserted into the housing base part (B) in an installation direction and is connected to the housing base part (B), wherein a checking means (P) for checking the assembly of the thermometer (TH) is arranged and mechanically fixed between the measuring insert (ME) and the housing base part (B) in such a way that the mechanical fixation of the checking means (P) is released when the measuring insert (ME) experiences a force directed against the installation direction.
The invention relates to a measuring transducer feed unit (1) for use in automation technology, which makes the connection of at least one field unit (3) to a superordinate unit (4) by means of a two-wire line (2) possible, wherein the measuring transducer feed unit (1) comprises at least a switch (5), a radio module (6), and a circuitry (7). The radio module (6) can be activated or de-activated by means of the switch (5), and the circuitry realizes the conversion between signals of the two-wire line (2) and signals of the radio module (6) such that the at least one field unit (3) connected to the measuring transducer feed unit (1) via the two-wire line (2) can be operated by wireless communications connection (13) by means of the radio module (6).
