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.
