Dead Weight Tester - Tungsten Carbide Piston And Non-magnetic Stainless Steel Weights | High Precision Calibration For Digital And Precision Pressure Gauges

Keeping track with market development, we are indulged in exporting, manufacturing and supplying an excellent quality collection of Dead Weight Tester in Xian, Shaanxi, China. Piston pressure calibrator (o also referred to as mechanical dead-weight testers ) 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 balanceA 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.
