JY series piston pressure gauge

Product Overview
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 currently the most cost-effective pressure reference equipment on the market. The piston pressure gauge produced by our factory is not limited to obtaining national calibration certificates, but also focuses on the convenience of measurement and use, making measurement efficiency higher and easier. This is our market positioning for piston pressure gauges.

Product Features

uMeets JJG59-2007 "Verification Regulations for Piston Pressure Gauge" and JJG99-2006 "Weights", as well as the National Metrological Verification Regulations.

uThe piston rod and piston cylinder are made of tungsten carbide material and finely ground to ensure good discernment of the piston.

uAdopting a low center of gravity structure, the piston system is more stable.

uThe piston system adopts a tungsten carbide integrated protection structure, with a protection shaft diameter of 10 millimeters. The protection shaft and piston rod are both made of tungsten carbide material and formed in one piece. Ensuring that the piston system is not damaged during use, this protection scheme is independently developed by our company to efficiently protect the piston system (invention patent).

uThe piston pressure gauge adopts an external displacement proximity sensor, which can display the real-time changes in the position of the piston system. The display system is a digital tube display, which is more intuitive. The piston displacement height is 0-3 millimeters. The external displacement system is not embedded in the piston system and does not affect the piston protection system.

uThe piston pressure gauge adopts a drainage system, and there are oil discharge pipelines below the piston system and output interface. The oil flows directly back to the oil cup, ensuring the cleanliness and hygiene of the piston table. The all-round oil discharge system far exceeds the single piston system, making the table more oil-free.

uThe piston cylinder adopts a self sealing system, and the sealing ring can ensure that there is no leakage after 30000 cycles of compression, truly achieving convenience and ease

uThe piston is equipped with a pre pressurization device, making pressurization easier

uThe piston pressure gauge has a pre pressurization device but no pre pressurization shut-off valve. The overall valve only has one pressure relief valve, making operation more convenient.
