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.
