Overview
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.
Pneumatic dead weight tester is pressure reference instrument with high accuracy, which media is air and can measure and calibrate gauge pressure, absolute pressure and vacuum.
Pneumatic dead weight tester is superior to hydraulic dead weight tester in perdurability, sensitivity, repeatability, accuracy.
