CE Certification 63mm Oil-Filled Bottom Mount Pressure Gauge - 1/4 BSP Brass from China Suppliers & Factory, Shock-Resistant Design Manufacturer, Supplier

,

A semi-stainless steel bottom oil-filled pressure gauge is an essential mechanical pressure measuring instrument designed for various industrial applications. Housed in durable stainless steel (commonly 304 or 316), this gauge is filled with a shock-absorbing fluid, such as silicone oil or glycerin, to enhance its performance. The pressure port, positioned at the bottom of the casing, allows for versatile installation. With its corrosion-resistant stainless steel construction and the vibration-damping properties of the oil-filled design, this gauge ensures accurate and reliable pressure monitoring even in demanding environments.

Core Characteristics and Advantages

Core Features and Advantages

High cost-performance ratio: Compared to "all-steel" watches (where all core components are stainless steel), it offers higher cost-performance while maintaining excellent corrosion resistance.

Oil Filling Advantages

  • Vibration reduction and shock resistance: Effectively buffers the impact of medium pressure pulsations and mechanical vibrations on the pointer and internal movement, preventing severe pointer jitter and ensuring clear and stable readings.
  • Lubrication and rust prevention: Lubricates transmission components, reduces wear, and isolates internal parts from air, preventing oxidation and corrosion.
  • Moisture and dust protection: Prevents condensation and dust from entering the watch, suitable for humid and dusty environments.
  • Extended lifespan: Significantly extends the instrument's service life under vibration and shock conditions.

Typical Application Fields

  • Hydraulic and pneumatic systems: Engineering machinery, injection molding machines, compressors, etc.
  • Fluid transport and process control: Water pumps, petrochemicals, water treatment, piping systems.
  • Mechanical equipment: Air conditioning and refrigeration equipment, ships, diesel engines.
  • Other harsh environments: Measurement points subject to vibration, media pulsation, or outdoor moisture protection requirements.

Frequently Asked Questions (FAQ)

Q: Why is this pressure gauge referred to as having a high cost-performance ratio?
A: It features a stainless steel case for external durability and corrosion resistance, while utilizing brass for internal connections and movements. This hybrid design offers a more budget-friendly solution compared to all-stainless steel gauges without sacrificing structural integrity.
Q: What are the benefits of oil filling (liquid filling) in this gauge?
A: Oil filling dampens mechanical vibrations and pressure spikes, which stabilizes the pointer for accurate readings. It also lubricates internal components, prevents moisture condensation, isolates dust, and significantly extends the service life of the gauge in harsh environments.
Q: Can this pressure gauge be used outdoors and in humid environments?
A: Yes. The stainless steel case combined with the oil filling provides excellent moisture and dust protection, making it highly suitable for outdoor installations and humid or dusty industrial settings.
Q: What media is this gauge compatible with?
A: Since the connection and Bourdon tube are made of brass, this gauge is suitable for non-corrosive fluids, air, water, and oil. It should not be used with media that corrodes copper alloys.
Q: What does the 1/4" BSP thread specification mean?
A: 1/4" BSP (British Standard Pipe) is a standard thread size widely used globally for pneumatic and hydraulic connections, ensuring easy compatibility with standard industrial piping systems.
