ABSTRACT:
Analog measured values are processed by an A/D converter (50) and/or digital measured values are processed by a timer (60) in a microcomputer and fed through a P/S converter (62) to a logic means (42). Furthermore, RF pulses are fed by an oscillator means (44) to an additional input of the logic means (42). The logic means (42) transfers the RF pulses of the oscillator means (44) to a transmitter (4) for wireless transmission of measured values whenever the P/S converter (62) feeds pulses to another input of the logic, the length and spacing apart of such pulses depending on the measured values.
