Beschreibung
Zusammenfassung:	transport engineering; checking air pressure in tires of moving tractor. SUBSTANCE: proposed device has toothed disks installed on corresponding wheels inductively coupled with tractor wheel turning angle converters. Measuring converter signal processing unit has comparator whose inputs are coupled with measuring converters through series connected frequency-to-voltage converters, time-setting circuits and diodes. Comparator has two threshold state being provided with feedback for changing threshold of operation. Frequency-to-voltage converters are made for stepless adjustment of transmission gains. Output of signal processing unit is connected with audio and light signaling elements. EFFECT: increased versatility and accuracy of checking. 2 cl, 1 dwg
