FIELD: measuring technology; particularly, devices measuring viscosity of small volumes of fluids changing from normal to high. SUBSTANCE: viscosimeter comprises two hydraulic cylinders 1 and 2 intercoupled by capillary device 3. Hydraulic cylinders 1 and 2 have pistons 4 and 5 installed in bodies 6 and 7, respectively. Each hydraulic cylinder is equipped with pressure transducer 8 and 9 and displacement sensor 10 or 11. Bodies 6 and 7 are attached to common base 12. Drive of piston 4 provides for translational-rotary motion of piston 4 by means of pair "screw 13 - nut 14" and, respectively, drive of piston 6, with the aid of pair "screw 15 - nut 16". Screw 13 is connected to piston 4 and to motor 17 and screw 15, to piston 5 and to motor 18. Bodies 6 and 7 are spring-loaded with flexible members 19 and 20 placed between face of body 6 and nut 14 and between face of body 7 and nut 16, respectively. Pressure transducers 8 and 9 are made for each hydraulic cylinder in the form of indicator registering mutual displacement of nut 14 and body 6, and nut 16 and body 7. displacement sensors 10 and 11 are made in the form of indicator registering mutual displacement of piston 4 and body 6, of piston 5 and body 7, respectively. EFFECT: multimode performance of measurements with increase of their accuracy. 3 cl, 9 dwg |
