CE Certification 4.5 160 PSI Common Rail Pressure Gauge - Reliable China Suppliers & Factory with Solid Front Phenolic Case Manufacturers, Factory

The pressure gauge is a highly precise mechanical device designed for accurate measurement and local indication of fluid or gas pressure across various industrial, commercial, and process applications. Crafted from durable materials like stainless steel or brass, this gauge promises long-lasting reliability even in challenging operating environments, including high vibration, temperature variations, and corrosive settings. Utilizing a Bourdon tube sensing element, the gauge effectively converts pressure into mechanical displacement, which is displayed through a finely calibrated dial and pointer, Offered in a range of dial sizes, pressure ranges, and connection types, these pressure gauges can be customized to meet the specific requirements of diverse systems. They find extensive use in industries such as oil & gas, chemical processing, water treatment, HVAC, power generation, and manufacturing. Optional features include glycerin or silicone fluid filling for damping, overpressure protection, adjustable zero mechanisms, and adherence to international standards like EN 837 and ASME B40.100, Manufactured in China by trusted suppliers, our factory ensures that each pressure gauge is easy to install and maintain, delivering stable performance, excellent readability, and an extended service life. This makes it a vital component for safe and efficient system monitoring

Core Features & Advantages

Durable Structure & Protection

The case is made of high-quality Phenolic material with rust-proof treatment, suitable for damp, dusty, and mildly chemically corrosive environments. Chrome-plated options are available, further enhancing protection. Glass and polycarbonate lens options provide strong impact resistance against mechanical collisions.

High Readability & Precision

The high-contrast white aluminum dial with clear black scales facilitates rapid reading from a distance. The black-finished aluminum pointer is lightweight and vibration-resistant, delivering accurate and drift-free indications. Stainless steel movement and Bourdon tube guarantee long-term measurement consistency.

Flexible Installation Options

Supports versatile mounting configurations (bottom inlet, middle rear inlet, bottom rear inlet) to fit various layout demands. Threaded interfaces support multiple standards including 1/8", 1/4", 3/8", and 1/2" across PT (BSPT/ZG), BSP (G/PF), and NPT options.

Broad Application Compatibility

Available in seven dial sizes ranging from 40mm (1.5") to 200mm (8"). Perfectly suited for embedding into compact equipment panels or installing on large industrial monitoring dashboards across pneumatic and hydraulic systems.

Typical Application Fields

  • Industrial Hydraulic & Pneumatic Control Systems
  • Compressors, Pump Valves & Pipeline Monitoring
  • Water Supply, Heating & Air Conditioning (HVAC)
  • Energy, Chemical & Manufacturing Process Control
  • Firefighting Equipment & Safety Systems
