Disclosed is a transmitter which achieves a permanently high security standard in an inexpensive manner. The inventive transmitter comprises a set of identically built sensors ( 1, 21, 23 ) for measuring a physical parameter, a set of electronic circuits ( 5 ), each of which is assigned to a sensor ( 1 ) and conditions an electrical signal that is generated by the assigned sensor ( 1 ) and corresponds to the physical parameter, and an output unit ( 17, 25 ) to which the conditioned electrical signals of all sensors ( 1 ) are fed. Said output unit ( 17, 25 ) generates a measuring signal from the conditioned electrical signals, makes said measuring signal available for further evaluation, processing, and/or display, and generates information about the plausibility of the measuring signal and/or information about the operability of the individual sensors ( 1 ).
