FIELD: physics; radio. ^ SUBSTANCE: invention is related to the field of telemetering systems and may be used for remote control of object parameters, in particular, temperature of railway wheelset bearings. Result is achieved by introduction of parameter control detector, current source and analog-digital converter into available tracer. As parameter detector, any electric radio element may be used, which has dependence of internal resistance from any parameter, for instance, thermal resistance. As ADC and identification code generator, microchip may be used with extremely low consumption, for instance, of PIC12F683 type. ^ EFFECT: possibility to remotely measure object parameters with application of passive tracers. ^ 5 cl, 1 dwg |
