FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building for diagnostics of cylinder-piston group of diesel engine, hydraulic pumps. Device comprises a means of measuring pressure of crankcase gases of a diesel engine, made in the form of low pressure and temperature sensors installed in an adapter, means of indicating measurement results in the form of a digital display, a microcontroller and an accumulator. It is equipped with an additional high pressure adapter with high pressure and temperature sensors, the adapters are connected to the microcontroller through the connector, microcontroller is connected to control keys, on indicator and switch of built-in accumulator or on-board network. Besides, it is equipped with interface connector of personal computer and telemetry terminal connected to microcontroller, and device housing is made in dust- and moisture-resistant housing.
EFFECT: increased accuracy of determination of technical state and operating conditions of engine and hydraulic pumps and reduced risk of accidents of main power transmission lines.
