Dead Weight Tester-CV series

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 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.
 
Applications:
1. Primary standard for defining the pressure scale in a range of up to 60MPa.
2. Pressure reference for factory and calibration lab for the testing, adjustment and calibration of pressure measuring instruments.
