Abstract: THE PURPOSE. The aim of the work is to develop an improved software and hardware complex for controlling the nozzle in the mechatronic oil analyzer PMRA-IV. The development should provide an accurate and stable supply of the test liquid to the PMR sensor when conducting multiphase analyzes of oil properties. The equipment must provide smooth movement of the nozzle in the measuring tank, be protected from electromagnetic interference, and also be compact and easy to operate. Control must be carried out using a program on a computer and a control panel. METHOD. For development, the operating principle of the sampler was investigated. Based on the technical documentation, the operating principle of the used SD-54 electric motor was studied. The communication protocol between the computer and the microcontroller that controls the electric motor has been studied. A control algorithm for moving the pipe has been studied. RESULTS. The result of the work is a developed compact pipe control device. Created: control software for a computer in the Labview environment, a control panel and a circuit solution to increase the noise immunity of the installation. Smooth movement of the pipe is provided using a remote control or a program on a computer via a USB connection. CONCLUSION. Comparison with previous designs shows that the sampling device with the new control system is more accurate, stable and smooth, and has multiple control methods. The development is capable of operating stably in the presence of electromagnetic interference arising from relay switching or the magnetic field arising around the motor. The new control device allows you to quickly and accurately select the required volume of liquid into the PMR sensor.
