Description
The DK series piston pressure gauge is a redesign and optimized
structure of our factory based on the YS series piston pressure
gauge and JY series piston pressure gauge, with super wear
resistance and perfect reliability. The DK series piston pressure
gauge has a maximum accuracy of 0.005% and a maximum range of
250MPa. The DK series adopts a modular structure, and one platform
can install different piston systems, achieving the purpose of
economic practicality.

Features
1. Modularization: The piston system and pressure generator have a
fully modular structure, and various modules can achieve single or
combined functions.
2. Stability: The wave body piston uses low position weights to
ensure high reliability and stability.
3. Interchangeability: The piston range can be freely interchanged
by replacing the sleeve unit.
4. Piston sleeve unit: Made of tungsten carbide material, other
parts are made of high-quality austenitic stainless steel, which
can effectively avoid deformation.
5. Weight: Made of demagnetized high-quality austenitic stainless
steel.
6. Rotation speed: In the free rotation state, the decay of
rotation speed is related to time. For example, for a 60MPa
product, the speed decreases from the initial 33.0rpm to 24.8rpm
after 30 minutes. This also indicates that the pressure
distribution of the piston sleeve clearance is uniform.
7. Effective area: The average effective area and pressure
deformation coefficient of the piston sleeve unit can be measured
by a reference pressure gauge under standard atmospheric pressure
and 20 ℃ conditions.
8. Piston descent speed: When the range is 60MPa, the piston
descent speed is linearly related to the pressure. At a range of
100MPa, for all components, the piston descent speed and effective
area are linearly related to pressure, with a maximum descent speed
of less than 5um/s and a maximum effective area change of less than
0.0006mm.
Instrument advantages
1. The pressurization system adopts a hard seal, does not rely on
O-ring sealing, does not require changing the skin bowl, does not
have pressure leakage problems, and does not require frequent
disassembly and assembly.
2. Pre pressurization without a valve, no need to close the pre
pressurization valve, simple operation.
3. The pressure system is hard sealed, with a thin pressure rod,
making it very easy to apply pressure to 100MPa with one hand.
