Product Advantages

Liquid Filled Vibration Dampening Design

Glycerin or silicone oil filling reduces internal vibration, ensuring stable pointer movement under pulsating hydraulic pressure.

High Pressure Stability (0–400 bar)

Designed for continuous high-pressure operation up to 5800 psi, ensuring mechanical stability under industrial load conditions.

Back Mount Compact Installation

Back connection design supports compact installation in control panels and hydraulic equipment with limited space.

Working Principle

The Bourdon tube deforms under applied pressure. This mechanical deformation is transmitted through a linkage mechanism to the pointer, which displays the pressure value on the dial.

FAQ

What is the advantage of 400 bar pressure rating?

It allows safe operation in high-pressure hydraulic systems such as pumps, jacks, and industrial machinery.

What is the benefit of back mount design?

Back mount installation is suitable for compact equipment panels and space-limited hydraulic systems.

What is the difference between glycerin and silicone oil fill?

Glycerin is suitable for general industrial use, while silicone oil performs better in temperature-variable environments.
