Nexisense YUNY-900A Electric Pneumatic Pressure Source: Efficient Electric Pressure Benchmark for Oil-Free Instrument High-Pressure Calibration
Product Overview
In the fields of petrochemical, natural gas, hydrogen energy, laboratory gas analysis, and high-pressure gas instrument calibration, oil-free instrument (oil-free lubrication) calibration places extremely high requirements on the safety, stability, and efficiency of pressure sources. Traditional manual pneumatic pressure sources suffer from large compression ratios, difficult pressurization, low efficiency, and high labor intensity. The electric pneumatic pressure source effectively solves these industry pain points through built-in high-pressure pumps and stepless speed regulation technology.
The Nexisense YUNY-900A electric pneumatic pressure source is a high-performance electric pressure source specially designed for oil-free instruments. The product features a built-in high-performance booster pump, with a maximum output pressure of up to 25MPa. It is also compatible with negative pressure mode, supporting continuous adjustment in a wide range from -0.1MPa to 25MPa. Electric pressure generation is achieved through knob adjustment, enabling precise control of the pressure rise rate, significantly improving calibration efficiency. It is particularly suitable for on-site calibration, laboratory verification, and batch calibration tooling of gas pressure instruments such as pressure transmitters, pressure sensors, and precision pressure gauges.
The product adopts an industrial-grade design, with a compact structure, convenient operation, safety and reliability. It is an ideal choice for engineering companies, system integrators, and metrology verification institutions to build gas pressure calibration systems.
