Abstract (en)

[origin: EP0627716A1] The invention relates to UHF radio transmission of measured values between consumption distributor devices (10) and a receiver circuit (1 - 6), assigned thereto, of a control centre (1 - 3, 5 - 9). So-called SAW components, that is to say surface acoustic wave resonators, are preferred as frequency-determining elements for the UHF transmitter circuits. With a view to possible, in particular temperature-induced frequency deviations of the UHF transmitters (10), the input of the receiver circuit (6) is maintained with a correspondingly broad bandwidth (Df). For interference suppression of external frequencies in this range (Df), there is now assigned to the receiver circuit (6) a scanner (3) which continuously scans the input band in a narrow-band (df) fashion in order to acquire signals which arrive from the consumption distributor devices (10) and which are as free as possible from external and interference signals. <IMAGE>
