Dead Weight Tester with nominal measurement range from 0.04 to 100 MPa suitable for various pressure calibration applications

The main and auxiliary integrated piston manometer is mainly used to test the piston manometer use, the main and auxiliary integrated piston manometer can be installed at the same time 2 piston head, one installs the standard piston head, one installs the inspected piston head, through the beginning of the balance method and other calibration methods, the area of the inspected piston system is calculated, and at the same time according to the percentile table to test the inspected piston drop data.
Nominal range/measurement range:
0.04~0.6MPa;0.1~6MPa;1~60Mpa;2~100MPao
Accuracy:
0.005 grade ( +0.005% ); 0.01 grade (+0.01%).
0.02 grade(+0.02%) ;0.05 grade(+0.05%).

Meet the JJG59-2007 “piston manometer calibration regulations” and JJG99-2006 “weights”, the national metrological calibration regulations.
The piston rod and piston barrel are made of tungsten carbide material with fine grinding to ensure the piston’s good discriminatory force.
Low center of gravity structure makes the piston system more stable.
The piston system adopts tungsten carbide one-piece protection structure, the diameter of the protection shaft is 10mm, the protection shaft and the piston rod are made of tungsten carbide, one-piece molding. Ensure that the piston system is not damaged in use, this protection program is our independent research and development can be highly effective protection of the piston system (patent pending).
Piston pressure gauge using external displacement close to the sensor, real-time display of changes in the position of the piston system, the display system for the digital tube display, more intuitive, the height of the piston displacement of 0-3 mm. The external displacement system is not embedded in the piston system and does not affect the piston protection system.
Piston manometer adopts a sewage system, in the piston system below the output interface below the oil discharge pipeline, oil directly back to the oil cup, to ensure the piston table clean and hygienic, all-around oil discharge system Far more than a single piston system oil discharge, so that the countertop is more oil-free
The piston cylinder adopts self-sealing system, the sealing ring can ensure 30,000 cycles of pressure without leakage, truly convenient and convenient.
The piston is equipped with pre-pressurizing device, which makes the pressurizing easier.
