YN40Z Series 40mm Stainless Steel Liquid Filled Pressure Gauge 400bar / 6000psi Shockproof Industrial Gauge

Product Overview

The YN63Z series liquid filled pressure gauge is a 40mm compact industrial instrument designed for accurate pressure measurement in hydraulic, pneumatic, and general industrial systems.

It uses a bourdon tube mechanism combined with a stainless steel case and liquid filling (glycerine or silicone oil) to ensure stable readings under vibration and pulsation conditions.

This model is widely used in hydraulic equipment, compressors, pump systems, and industrial machinery where durability and shock resistance are required.

Key Features & Advantages

Shockproof Liquid Filled Design

Filled with glycerine or silicone oil to reduce vibration and improve reading stability.

High Pressure Capability

Suitable for 400 bar / 6000 psi high pressure industrial environments.

Stainless Steel Durable Case

Corrosion resistant structure suitable for harsh working conditions.

Accurate Bourdon Tube Measurement

Reliable mechanical pressure sensing system with long service life.

Cost-Effective Industrial Solution

Economical alternative to high-cost imported pressure gauges.

Working Principle

The bourdon tube deforms under pressure and drives the pointer through a mechanical linkage system. The liquid filling dampens vibration to ensure stable and accurate readings.

Important Note

This is a mechanical bourdon tube pressure gauge. It does not include electrical contact switching or digital output functions.
