40MPa Vibration Proof Liquid Filled Pressure Gauge 0-400kg/cm2 Back Mount Pressure Gauge
40MPa Vibration Proof Liquid Filled Pressure Gauge 0-400 kg/cm² Back Mount Stainless Steel Industrial Gauge
Product Overview
The 40MPa vibration proof liquid filled pressure gauge is designed for hydraulic systems and industrial equipment operating under high pressure and dynamic load conditions.
It uses a Bourdon tube sensing mechanism combined with a stainless steel sealed case and glycerin or silicone oil filling medium. The liquid filling reduces vibration impact and improves pointer stability under pulsation pressure.

Product Advantages
Vibration Dampening Liquid Filled Design
Glycerin or silicone oil filling absorbs vibration and pressure pulsation, improving readability under dynamic hydraulic conditions.
High Pressure Capability (40MPa)
Designed for continuous operation under high pressure up to 40MPa,suitable for demanding hydraulic environments.
Back Mount Compact Installation
Back connection design allows installation in compact hydraulic panels and space-limited equipment structures.
Working Principle
The Bourdon tube deforms under pressure and converts mechanical displacement into pointer movement through a linkage mechanism.
The liquid-filled chamber dampens internal vibration energy, stabilizing the pointer under fluctuating hydraulic pressure.
