FIELD: engines and pumps.
SUBSTANCE: proposed device serves to diagnose positive-displacement hydraulic machines and systems, including those of mobile machine control and braking. It comprises pressure line 1 connected with surplus pressure source (pump) 2. Adjustable throttle 3 and solenoid-type hydraulic control valve 4 is arranged in said pressure line 1. Pickup 5 housing triboelectric elements-screens 6 connected with recorder 7. Screens 6 are made from material with permittivity exceeding that of analyzed fluid. Hydraulic control valve 4 communicates, via hydraulic lines 8, with hydraulic cylinder 9. The latter has its rod supporting work member 10 and communicates, via hydraulic line 11, with tank 12 whereto hydraulic line 13 is connected.
EFFECT: higher accuracy of measurements.
