Stainless Steel Back Mount Pressure Gauge 63mm Glycerin filled
63mm Stainless Steel Back Mount Pressure Gauge Glycerin Filled EN 837-1
Product Overview
This 63mm stainless steel back mount pressure gauge is a glycerin-filled Bourdon tube instrument designed for stable and reliable pressure measurement in vibration-prone industrial environments.
Manufactured according to EN 837-1 standard, the gauge uses a mechanical Bourdon tube system to deliver accurate pressure readings without electrical power. The glycerin filling helps dampen pointer vibration, making it suitable for pumps, compressors, hydraulic systems, and HVAC applications.
The stainless steel case provides corrosion resistance and long service life, while the back mount (center rear connection) allows easy panel installation in OEM equipment and industrial control systems.

Key Advantages
1. Glycerin Filled Anti-Vibration Design
Reduces pointer fluctuation and improves readability in high vibration environments.
2. Stainless Steel Corrosion Resistance
Ensures long-term durability in humid, industrial, and outdoor applications.
3. Compact 63mm Industrial Size
Balanced size suitable for both OEM integration and general industrial use.
4. Back Mount Installation
Center rear connection allows easy panel or machine installation.
5. EN 837-1 Compliance
Manufactured according to international mechanical pressure gauge standards.
Working Principle
The Bourdon tube inside the gauge deforms under pressure. This mechanical movement is transmitted to the pointer system. The glycerin filling dampens mechanical vibration, ensuring stable reading under pulsation conditions.
