The article focuses on the choice of a reliable source of electric power for the wireless dynamograph. The essence of the problem lies in the fact that the force sensor wireless dynamograph for it’s work requires energy proportional to the frequency of the largest swing of the polished rod of sucker rod pumps. At high frequency oscillation (small period) used conventional sources of electricity are ineffective. In this paper a solution is proposed as a piezoelectric generator which converts the mechanical energy from the changing load on the polished rod to the required electrical energy.Downloads
