English Product Description:
The YB150A Precision Vacuum Pressure Gauge is a high-accuracy measuring instrument designed for both positive pressure, negative pressure, and vacuum degree monitoring in industrial equipment and laboratory environments. Featuring an advanced elastic sensing element structure, this gauge delivers reliable performance across diverse operating conditions.
This pressure gauge excels in two key aspects: measurement accuracy and mechanical construction. With a 0.4-class precision rating, it maintains minimal measurement deviation across its broad operational range. The stainless steel housing incorporates a dual-layer shockproof sealing mechanism, effectively mitigating environmental vibrations, medium pulsations, and humidity impacts. The anti-glare dial with high-contrast graduations and corrosion-resistant pointer ensures clear visibility under low-light conditions, enabling quick and accurate readings.
Functionally, the YB150A supports bidirectional pressure measurement, covering vacuum ranges from -0.1 to 0 MPa and positive pressure up to 150 MPa. Its thermally compensated elastic sensing element minimizes temperature-induced measurement drift, guaranteeing consistent performance over extended periods. Special surface treatment on critical components enhances resistance to wear and medium compatibility.
Ideal for petrochemical systems, precision machinery, pharmaceutical production lines, and scientific research applications, this gauge particularly excels in vacuum-sensitive processes such as semiconductor fabrication and advanced material testing. Users are advised to implement regular calibration and avoid overpressure exposure or contact with corrosive substances to optimize service life.
