100mm All Stainless Steel Water Pressure Gauge Glycerin Filled EN 837-1 Industrial Manometer

Product Overview

This 100mm stainless steel water pressure gauge is designed for industrial and commercial water systems where durability, vibration resistance, and stable measurement are required.

The gauge is manufactured in compliance with EN 837-1 standard and uses a bourdon tube sensing element to provide reliable mechanical pressure indication without external power supply.

The case is fully stainless steel (SS304) with optional SUS316 wetted parts, making it suitable for water, air, hydraulic fluids, and general industrial media.

A glycerin-filled design significantly reduces vibration and pulsation effects, ensuring stable pointer movement and longer service life in pump systems and dynamic environments.

Key Advantages

Glycerin Filled Anti-Vibration Design

The liquid-filled case reduces vibration and pulsation effects, improving readability and extending service life in pump and hydraulic systems.

100mm Large Dial for Easy Reading

Large dial design improves visibility in industrial environments and supports fast pressure reading.

All Stainless Steel Construction

SS304 housing with optional SS316 wetted parts ensures corrosion resistance in water and industrial environments.

EN 837-1 Standard Compliance

Manufactured according to international EN 837-1 standard for reliable mechanical pressure measurement.

Industrial Reliability

Suitable for continuous operation in water pump and HVAC systems with stable mechanical performance.

Working Principle

The bourdon tube inside the gauge deforms under pressure. This mechanical movement is transmitted through a linkage mechanism to rotate the pointer on the dial.

The glycerin filling dampens internal vibration, ensuring smooth pointer movement under fluctuating pressure conditions.
