Liquid Filled Pressure Gauges

Liquid-filled pressure gauges are designed for pressure measurement in applications exposed to vibration, pulsation, and mechanical shock. The gauge case is filled with glycerin or silicone oil, while an internal Bourdon tube responds to system pressure and drives the pointer to display the measurement value.

Dry Pressure Gauges

Bourdon tube pressure gauges are mechanical instruments used for the measurement of gauge pressure in non-liquid-filled systems. The Bourdon tube bends under pressure and moves a mechanical linkage that drives the pointer on the dial.

Capsule Pressure Gauges

Capsule pressure gauges use a metal capsule as the sensing element to measure very low pressures. When pressure acts on the capsule, it expands or contracts slightly. This movement is transferred through a mechanical linkage system to drive the pointer on the dial, indicating the pressure value.

Differential Pressure Gauges

Differential pressure gauges are used to measure the pressure difference between two points in a system. They are designed to display small or large pressure variations between inlet and outlet lines or between two connected measurement points.

Special Application Gauges

Special application gauges are designed for industries where standard pressure gauges cannot meet operating requirements. These gauges are used under conditions involving high pressure, strong corrosion, vibration, high temperature, or high accuracy demands.

Digital Pressure Gauges

Digital pressure gauges are widely used in industrial automation systems, hydraulic and pneumatic systems, pipelines and pressure vessels, water treatment systems, construction machinery, laboratory calibration, medical equipment, and commercial devices requiring real-time and accurate pressure monitoring.
