Supply of tungsten carbide piston gauge

Piston gauge is a high degree of accuracy based on Pascal's law and the principle of hydrostatic equilibrium produced, high reproducibility and high reliability standard pressure gauge. Piston gauge is also often referred to as the piston gauge or pressure gauge, also known as pressure balance, mainly used for measuring room, laboratory and manufacturing or scientific labs use as a pressure reference device, there will be directly applied to piston gauge High reliability monitoring other aspects of the local vote monitoring instruments. Piston and cylinder made of high strength, low alloy steel of high hardness and temperature coefficient of linear expansion, tungsten carbide and other materials, thermal expansion coefficient is small, a small amount of deformation, thus ensuring periodic rate of change of the piston is small in size in order to ensure the effective piston pressure namely high sensitivity. In line with "JJG59-2007 piston gauge", "JJG99-2006 weights" national verification procedures. Rod: WC (Steel) piston cylinder: tungsten carbide (carbon steel) to choose weight material: 0.02% 0.05% stainless steel measuring range: 0.04 ~ 0.6MPa; 0.1 ~ 6MPa; 0.5 ~ 25Mpa; 1 ~ 60Mpa; Accuracy: 0.005 (± 0.005%); 0.02 级 (± 0.02%); 0.05 级 (± 0.05%)
