CE Certification 4.5 160 PSI Common Rail Pressure Gauge - Reliable China Factory with Premium Quality and Leading Suppliers Supplier, Factory

,

The pressure gauge is an essential precision mechanical instrument used for accurate measurement and local indication of fluid or gas pressure, making it ideal for various industrial, commercial, and process applications. Manufactured by leading suppliers in China, these gauges are constructed from durable materials such as stainless steel or brass, ensuring long-term reliability even in demanding environments characterized by high vibration, temperature fluctuations, and corrosive conditions. With a Bourdon tube sensing element, our pressure gauges convert pressure into mechanical displacement, displayed clearly via a calibrated dial and pointer.

,

Our pressure gauges are available in a wide range of dial sizes, pressure ranges, and connection types, allowing for customization to suit diverse system requirements. They are extensively used across multiple sectors, including oil & gas, chemical processing, water treatment, HVAC, power generation, and manufacturing. Optional features include glycerin or silicone fluid filling for enhanced damping, overpressure protection, adjustable zero mechanisms, and compliance with international standards such as EN 837 and ASME B40.100.

,

Designed for simple installation and maintenance, our pressure gauges deliver stable performance, excellent readability, and a long service life. As a trusted factory in China, we are committed to providing high-quality solutions for safe and efficient system monitoring, making our pressure gauges an indispensable component in your operations.

Core Features and Advantages
Durable Structure & Protection Design

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 appearance and protection level. Glass and polycarbonate (PC) lens options provide strong impact resistance for environments where mechanical collisions may occur.

High Readability & Precise Indication

The white aluminum dial with black scales offers clear contrast, facilitating data reading from a distance or in low-light conditions. The aluminum alloy pointer with black surface treatment is lightweight and resistant to shaking, ensuring stable indication. The movement and bourdon tube feature precise transmission structure and sensitive response for consistent measurement over time.

Flexible Installation & Connection Adaptability

Supports multiple installation positions — bottom inlet, middle rear inlet, and bottom rear inlet — to meet different system layout requirements. Threaded interfaces are compatible with 1/8", 1/4", 3/8", and 1/2" specifications, and can be provided with PT (BSPT/ZG), BSP (G/PF), NPT, and other thread standards, greatly enhancing system integration flexibility.

Wide Range of Applications & Multiple Sizes

Dial sizes cover seven specifications ranging from 40mm (1.5") to 200mm (8"), suitable for embedding into compact equipment panels or using on large units and remote monitoring dashboards. This meets the full range of pressure monitoring needs, from fine pneumatic control to heavy-duty hydraulic systems.
