40mm Radial Oil Filled Pressure Gauge 0-4MPa Stainless Steel Case Class 2.5

Product Overview

The 40mm Radial Oil Filled Pressure Gauge is a compact and reliable pressure measuring instrument designed for industrial environments where vibration, pulsation, and mechanical shock may affect measurement stability. Featuring a stainless steel case, liquid-filled damping system, and radial bottom connection, this gauge provides clear and stable pressure readings even under demanding operating conditions.

Technical Specifications

Key Features

· Liquid / Oil Filled for superior shock resistance

· Color-coded safety zones (Yellow/Green/Red) for quick visual reference

· Stainless steel construction for corrosion resistance

· Brass connections for reliable sealing

Working Principle

This pressure gauge operates using a Bourdon tube sensing element.

1. Process pressure enters the gauge through the connection port.
2. The Bourdon tube expands proportionally to the applied pressure.
3. The movement is transmitted through a precision linkage mechanism.
4. The pointer rotates across the calibrated dial scale.
5. The current pressure value is displayed in real time.

FAQ

What is the benefit of an oil-filled pressure gauge?

Oil filling reduces pointer vibration, improves readability, and extends the lifespan of the pressure gauge.

Can this gauge be used on air compressors?

Yes. The oil-filled design is particularly suitable for compressor applications where vibration is present.

Is this pressure gauge suitable for hydraulic systems?

Yes. The 0–4MPa pressure range is suitable for many hydraulic and fluid power systems.

Why choose a stainless steel case?

Stainless steel improves durability and helps protect the gauge from mechanical damage and industrial environments.

What is a radial mount pressure gauge?

A radial mount gauge has a bottom connection that allows direct installation onto pipelines, manifolds, and equipment.
