Ultra High Pressure Dead Weight Tester - Model CW-2500T

     
    Measuring range:(5~250)MPa   (50-2500)bar

     Accuracy: 0.005%; 0.01%; 0.02%;   0.05%



 
Application      
1.primary standard for defining the pressure scale in a range of up to 250MPa
2. pressure reference for factory and calibration lab for the testing, adjustment and calibration of pressure measuring instruments.
 
Working Principle:
Mechanical dead-weight testers or primary standards are the most accurate reference instruments for pressure. Their functional principle is based on the physical principle of pressure = force/area. Mass pieces placed on the top of a piston-cylinder system are the source of a precisely defined force. By producing a certain (counter) pressure inside the pressure balance an equilibrium is achieved: the mass pieces, including the free-running piston of the piston-cylinder system, are floating, which will lead to a very accurate pressure at the test port.
 

Features         
 
  •   The weights can be driven to 250MPa with engine at once.
  •   The dirty medium oil can be drained out from sewage outlet when it gets dirty.
  •   The piston rod is anti breakage structure and adopts spacing ring structure to reduce friction, so it is strong and rotates steadily.
  •   The gauge adopts military grade sealed structure to completely avoid oil leakage.
  •   The base is stainless steel material and  is assembled 3.5” TFT LCD display which can display piston working location, temperature and humidity, etc.
