In the realm of pressure measurement, piston pressure calibrator have long been pivotal in calibrating pressure parameters. Renowned for their high precision and stability, these instruments are extensively used for verifying various pressure sensors, pressure transmitters, digital pressure gauges, and other precision pressure instruments.

While accuracy and stability are the core values of any piston pressure calibrator, these qualities alone are no longer sufficient to stand out in today’s competitive market. The new piston pressure calibrator from Xi’an Yunyi not only meets these basic requirements but also excels in cost-effectiveness, convenience, and ease of use.

Introduction to the New piston pressure calibrator

Xi’an Yunyi’s new piston pressure calibrator is designed and manufactured in accordance with the latest national verification procedures for piston pressure calibrators (JJG59-2022 “Verification Regulation for Liquid piston pressure calibrators”). The use of tungsten carbide materials, known for their high hardness and low thermal expansion coefficient, significantly enhances the wear resistance of the piston, ensuring minimal deformation under pressure and exceptional stability. The working medium for the piston is di-2-ethylhexyl sebacate, which provides the gauge with exceptional sensitivity. With the adoption of new materials, technologies, and processes, the technical specifications of this new piston pressure calibrator have greatly improved, making it ideal for calibrating digital pressure gauges, precision pressure gauges, pressure transmitters, and pressure sensors.

Product Advantages

• Comprehensive Oil Drainage System

Equipped with an oil drainage system beneath the pressure gauge connector and the piston system, this piston pressure calibrator filters and directs the oil back into the oil cup. This design not only ensures the cleanliness of the oil, reducing contamination and waste but also enhances the hygiene of the equipment, making it suitable for environments with high cleanliness requirements.

• Integrated Anti-Break Structure

Compared to similar products, the integrated anti-break structure of this gauge effectively prevents piston rod breakage. This design improves the durability of the equipment, reduces maintenance costs, and provides operators with peace of mind, lowering the skill level required for operation.

• Innovative Pre-Pressurization Device

The piston pressure calibrator features a pre-pressurization device that operates without the need for a pre-pressurization shut-off valve, simplifying the operation process. This innovation speeds up calibration, reduces maintenance workload, and enhances work efficiency. As the only domestic manufacturer capable of achieving this feature, Xi’an Yunyi demonstrates its leading technical prowess.

• Comprehensive Protection Design

The protective floor beneath the piston provides additional safety, effectively preventing accidents. This comprehensive protection design ensures the equipment is safer and more reliable, meeting the high safety requirements of users.

Applications

piston pressure calibrators are widely used across various industries and fields. Here are some typical application areas:

• Chemical Industry: Used to monitor pressure levels in chemical reactors and the pressure changes during reactions.
• Pharmaceutical Industry: Used to monitor pressure changes in pharmaceutical machinery to ensure production quality.
• Food Processing Industry: Used to monitor pressure levels in processing equipment, ensuring food safety and product quality.
• Mechanical Processing Industry:Used to monitor hydraulic and pneumatic levels in machinery, adjusting the operating state of machines to enhance efficiency.

In summary, piston pressure calibrators are commonly used tools for measuring pressure and play a crucial role in many fields. Understanding their principles and applications is important for professionals and engineers across various industries.

Precautions:

• Maintain Cleanliness:Regularly keep the pressure gauge clean and avoid placing it in overly humid environments to prevent rust.
• Check Seals: Fast connectors and the O-ring at the bottom of the piston cylinder are prone to damage. Replace them if leakage is detected.
• First Use:When using for the first time, open the pressure gauge connector and allow oil to rise from the connector before attaching the gauge. This process is mainly to expel air.
• Pressure Release: Do not open the pressure release valve directly. First, turn the pressurization rod counterclockwise to allow the piston rod to descend gently, then open the release valve to avoid rapid descent of the piston rod that could cause damage.

The piston pressure calibrator from Xi’an Yunyi showcases exceptional performance and advantages in oil drainage systems, anti-break structures, pre-pressurization devices, and protective designs. These features not only enhance the overall quality of the product but also meet user demands for convenience, durability, and safety. We believe this piston pressure gauge will become a market leader, providing users with an outstanding experience
