Standard Bellows Pressure Gauge

Bellows Pressure Gauge uses a diaphragm as a sensitive element for measuring minute pressures. It measures low and negative pressures in gases that are non-corrosive to copper alloys and non-explosive. It is widely used in cobalt furnace ventilation, gas pipelines, combustion equipment, and other similar equipment.


Bellows Pressure Gauge consists of a measuring system (including connectors, diaphragm), a transmission mechanism, an indicating device, and a housing.When the pressure of the measured medium acts on the diaphragm, its free end undergoes a corresponding elastic deformation—displacement. This displacement is amplified by a lever-driven transmission mechanism, and the indicating device displays the measured pressure on the instrument dial.

High-Precision Measurement

Our advanced design, combined with a precision transmission mechanism, ensures measurement accuracy within ±0.5% FS (full scale), meeting the high-precision monitoring needs of low and negative pressures in industrial production, such as gas pipeline pressure monitoring and ventilation system pressure regulation.

 

Material and Corrosion Resistance

Bellows material: Copper alloy or stainless steel can be selected based on the medium characteristics. Copper alloy bellows are suitable for measuring non-corrosive gases or neutral liquids, offering high cost-effectiveness. Stainless steel bellows offer enhanced corrosion resistance and are suitable for chemical and coastal environments, effectively resisting corrosion from media such as acidic gases and humid steam.

 

Housing and Seals

The housing is constructed of stainless steel with an IP65 rating, offering excellent dust and moisture resistance. Seals are made of nitrile rubber or silicone, specifically designed for oil and high-temperature resistance, respectively, ensuring long-term stable operation.

 

Structural Design and Reliability

Compact Design: Its compact size allows for easy installation, making it ideal for space-constrained industrial equipment or piping systems.

 

Vibration and Interference Resistance

The optimized mechanical structure and transmission system effectively minimize the impact of vibration and electromagnetic interference on measurement accuracy, ensuring stable operation in complex industrial environments.

 

Certifications and Compliance

Our Standard Bellows Pressure Gauges are CE-certified, meeting EU market access requirements. They also comply with other international standards, such as ISO 9001 quality management system certification, providing reliable quality assurance for global customers.

    Stainless Steel Industrial Pressure Gauge

    The Stainless Steel Industrial Pressure Gauge consists of a pressure-guiding system (including connectors, spring tube, etc.), a gear transmission mechanism, an indicating device, and a housing. All components are made of stainless steel. When the spring tube is subjected to the pressure of the measured medium, its end undergoes corresponding elastic deformation, which is amplified by the gear transmission mechanism and displayed on the dial by the indicating device. The Stainless Steel Industrial Pressure Gauge's housing is sealed, effectively protecting the internal components from environmental influences and contaminants. Furthermore, the oil filling inside the housing provides resistance to pressure fluctuations of the measured medium and severe vibrations in the operating environment, ensuring both corrosion resistance and shock resistance.

    Nickel chrome wire

    Nickel chrome wire is a kind of non-magnetic alloy of nickel and chromium, it is widely used in heating elements. The maximum operation temperature of the heating elements is related to the wire diameter of Nickel chromium wire, it is better to choose thicker wires, the corrosive atmospheres also have a considerable relationship with the maximum operation temperature. The surface temperature of Nickel chromium wire is about 100C higher than the inner normally, when the operation temperature exceeds the limit, the oxidation of heating elements itself is accelerated, the heat resistance will be reduced, which is easily deformed,collapsed and even appreas to be broken, thereby shortening the service life of Nickel chromium wire.
