Y-63/100/150B stainless steel pressure gauges

The stainless steel pressure gauge uses a 316L all-stainless steel structure and high-precision conduit tubes, providing stable and reliable pressure monitoring in harsh environments such as chemical, petroleum, pharmaceutical, and food industries. The enclosure protection rating reaches IP65, with optional oil-filled shock resistance, a range covering -0.1MPa ~ 100MPa, accuracy starting from grade 1.6, supporting various threaded and flange connections.

Why choose stainless steel pressure gauges?

• Outstanding corrosion resistance: Both the liquid-connecting components and the casing are made of SUS304/316L stainless steel, resistant to acids, alkalis, salt spray, and humid environments.

• Suitable for harsh working conditions: fully sealed structure, dustproof and waterproof; After filling with glycerin or silicone oil, it effectively cushions mechanical vibrations and pressure pulsations.

• Ultra-high precision and stability: Accuracy level 1.6 (optional 1.0), no drift during long-term operation, reducing maintenance costs.

• Flexible customization: Range, dial diameter (63/100/150mm), mounting methods (radial, axial, flange), thread specifications (M20×1.5, G1/2, NPT1/2) can all be customized as needed.

Core parameters overview

Detailed explanation of technical advantages

Premium 316L spring tube: Uses laser welding and heat treatment processes, offering good linearity, low tolerance, and a lifespan of one million pressure cycles.

Explosion-proof and safety design: The dial is equipped with overpressure limit pins, and the pressure relief holes on the back plate prevent glass from splashing if the spring tube breaks, meeting safety standards.

Multiple scale options: supports MPa/psi dual scale, bar, kg/cm², and other units to meet different export and domestic needs.

How to choose the right model?

1. Determining the range: Under stable pressure conditions, the maximum range is 1.5 times the working pressure; under fluctuating pressure conditions, it is twice the working pressure.

2. Connection Selection: Radial direct installation is suitable for panels; Axial strip flanges are suitable for confined spaces.

3. Determine whether oil filling is needed: When there is strong vibration or instantaneous pressure pulses on site, the oil-filled shock-resistant type is recommended.

4. Confirm the corrosiveness of the medium: Standard 316L can resist most acidic and alkaline media; special media can be made of Hastelloy or PTFE separators.

Frequently Asked Questions (FAQ)

Q: Is there a big price difference between stainless steel pressure gauges and ordinary pressure gauges?
 A: Due to higher materials and craftsmanship, the price is about 1.5~2 times that of ordinary pressure gauges, but the service life is 3~5 times longer, resulting in lower overall long-term costs.

Q: Can it be used as an oxygen or hydrogen medium?
 A: Yes, but you must use the oil-free version and use a degreasing cleaning process. Please specify when ordering.

Q: What is the usual shipping lead time?
 A: Standard specifications have ample stock, ships within 2~3 days; Custom products (flanges/special scales) take about 7~15 days.
