High Accuracy 100mpa Hydraulic Dead Weight Tester Pressure Calibrator
Description High Accuracy 100mpa Hydraulic Dead Weight Tester Pressure Calibrator
As the most important pressure reference instrument, the piston pressure gauge is mainly used to calibrate other pressure instruments. It is one of the pressure reference instruments and the most cost-effective pressure reference equipment on the market. The piston pressure gauge produced by our factory is not only Confined to obtaining the national verification certificate, we focus more on the convenience of measurement and make the measurement efficiency higher and easier is our market positioning for the piston pressure gauge.

Comply with JJG59-2007 "Verification Regulations for Piston Pressure Gauges" and JJG99-2006 "Weights" and National Metrological Verification Regulations.
The piston rod and the piston barrel are made of tungsten carbide material and finely ground to ensure a good identification of the piston.
Using a low center of gravity structure, the piston system is more stable.
The piston system adopts a tungsten carbide integrated protection structure. The diameter of the protection shaft is 10 mm. The protection shaft and the piston rod are made of tungsten carbide and are integrally formed. To ensure that the piston system is not damaged in use, this protection scheme is independently developed by our company to effectively protect the piston system (inventive patent application).
The piston pressure gauge adopts an external displacement proximity sensor, which can display the position change of the piston system in real time. The display system is a digital tube display, which is more intuitive. The displacement height of the piston is 0-3 mm. The external displacement system is not embedded in the piston system and does not affect the piston protection system.
The piston pressure gauge adopts a sewage system. There are oil drain lines under the piston system and under the output interface, and the oil is directly returned to the oil cup to ensure the cleanness and sanitation of the piston table. The omnidirectional oil drain system far exceeds the oil drain of a single piston system. , Make the countertop more oil-free.
The piston cylinder adopts a self-sealing system, and the sealing ring can ensure that the pressure does not leak after 30,000 cycles, which is truly convenient and convenient.
The piston is equipped with a pre-pressurization device to make pressing easier
The piston pressure gauge has a pre-pressurization device but no pre-pressurization shut-off valve. The overall valve has only a pressure relief valve, which is more convenient to operate.
