The substantiation of the need for the preparation of thermal hydraulic drive road construction machinery (SDM) operating in the North. Given that a significant number of failures falls on hydraulic drive elements, it becomes urgent need to study their work and causes of failures. In order to analyze the thermal training funds, the development of new systems is necessary to study thermal characteristics of hydraulic drive elements SDM operated at low subzero temperatures. It is necessary to take into account the rate of change of the processes occurring in the hydraulic drive. In accordance with the above requires a quality measuring equipment, created on the basis of analog-to-digital converters. For this analysis instrumentation for experimental studies. Currently, at the Department of Transportation and technological systems developed hardware and software for temperature measurement system for monitoring hydraulic drive elements SDM.
