Introduction
This series of piston manometer is a high accuracy, high reproducibility and high reliability standard pressure measuring instrument produced by the principle of hydrostatic equilibrium. Piston pressure gauge is also often referred to as piston pressure gauge or pressure gauge, also known as pressure balance, mainly used in measuring rooms, laboratories, etc., as a benchmark instrument for verifying precision pressure gauges and sensors. The piston pressure gauge is also directly applied to the voting monitoring of other local instruments in the high reliability monitoring link.
Performance characteristics
Fully in line with JJG59-2007 "piston pressure gauge", JJG99-2006 "Weights" national metrological verification regulations, The piston and piston cylinder are finely ground, and the roundness error and gap are very small. The working medium uses low viscosity sebacic acid grease, which greatly improves the piston rotation duration, correspondingly reduces the piston decline speed and improves the piston discrimination. The piston working position is monitored visually, which has the advantages of eye-catching and accurate. The weights have been corrected for pressure deformation coefficient and local gravitational acceleration. Only need to send the piston measuring system for inspection, small size and light weight.
