  Dk Piston type Dead Weight Tester

 

1.specification

 

Description of Dk Piston type Dead Weight Tester :

DK series piston type pressure gauge is in our factory YS series piston manometer, KY series piston type pressure gauge, on the basis of structural optimization, with super abrasion and perfect reliability.DK series piston pressure gauge the progress of 0.005%;160 mpa. The maximum range of DK series adopts modular structure, a platform can install different piston system, achieve the goal of economical and practical.

Features of Dk Piston type Dead Weight Tester :
1,Modularity: Piston and pressure generator system is fully modular structure, the various
modules can implement a single function or a combination of work
2,Stability: hydraulic piston using low weights to ensure high reliability and stability.
3, Interchangeability: - any piston - sleeve unit
4,Piston - sleeve unit: made of tungsten carbide materials; other parts made of high quality
austenitic stainless steel, which can effectively prevent deformation. There are six ranges for choose 

5,Weight: Adopts demagnetization quality austenitic stainless steel
6,Rotational speed: in free rotation state, the rotational speed is related to the time, e.g. 60MPa
product, after 30 minutes, the rotational speed is from the initial speed of the drops 33.0RPM to
24.8rpm. This also shows that the piston - sleeve gap pressure distribution is uniform.
7,Effective area: under normal atmospheric pressure and 20 ℃ conditions, the piston - the
average effective area of the cartridge unit, and pressure deformation coefficient can be measured by
the reference gauge
8,Piston descending speed: in the range of 60MPa case, the relationship between the piston speed
and the pressure drop is shown below. In the range of 100MPa case for all of the components, the

rate of decline and the effective piston area of pressure become a linear relationship, the maximum
rate of decline is less than 5μm/s. Maximum effective area changes is less than 0.0006mm2.
