BOURDON

BOURDON is a brand with a history dating back to the mid-19th century, associated with the invention of the Bourdon tube pressure sensing element. The company manufactures a range of pressure measurement instruments, including mechanical pressure gauges, diaphragm seals, and thermometers. BOURDON products are used in industrial applications where reliable pressure indication is required, such as in oil and gas, chemical processing, power generation, and water treatment. The product line includes all-stainless steel wetted parts and casing gauges, like the 437U series, which feature a 4 1/2 inch dial, white face, black pointer, and bottom connection with 1/2 inch NPT male thread. These gauges offer an accuracy of ±0.5% and are available in pressure ranges from 0 psi to 600 psi. The case material is plastic, providing corrosion resistance in moderate environments. BOURDON gauges are designed for panel-mount installation, making them suitable for control panels and monitoring stations. 3G Electric supplies BOURDON pressure gauges to plant engineers, maintenance managers, and procurement specialists globally. The inventory includes multiple SKUs within the 437U series, covering common pressure ranges for process monitoring. 3G Electric provides logistics support for sourcing these instruments, ensuring availability for scheduled maintenance or new installations. The gauges are built to standard industrial specifications, with wetted parts made from stainless steel for compatibility with a variety of media, including gases and liquids. The Bourdon tube mechanism is a helical or C-shaped tube that deflects under pressure, translating to a rotary movement of the pointer. This design is widely used for its simplicity and durability in static pressure measurement. BOURDON gauges are not intended for dynamic or pulsating applications without additional dampening. The brand is recognized in the instrumentation industry for its adherence to basic measurement standards, though specific certifications are not claimed here. For procurement, engineers should verify the required pressure range, connection size, and dial size to match the application. 3G Electric supports the line by offering a selection of BOURDON gauges that meet common industrial requirements, with the ability to quote for larger quantities or alternative specifications.

Frequently asked questions

Common questions about BOURDON from 3G Electric.

What is the accuracy specification of BOURDON 437U series pressure gauges?

The BOURDON 437U series pressure gauges have an accuracy of ±0.5% of full scale. This means for a gauge with a 300 psi range, the reading is accurate within ±1.5 psi. This accuracy class is suitable for general industrial monitoring where precise measurement is required but not for calibration-grade applications.

What materials are used for the wetted parts and casing in BOURDON all-stainless steel gauges?

In the BOURDON 437U series, the wetted parts (the Bourdon tube and connection) are made from all-stainless steel, providing corrosion resistance for use with many process fluids. The casing is made from plastic, which offers lightweight protection and resistance to environmental corrosion, though it is not suitable for high-temperature or highly corrosive external environments.

What pressure ranges are available for the BOURDON 437U panel-mount gauge?

The BOURDON 437U series is available in multiple pressure ranges, including 0 to 60 psi, 0 to 100 psi, 0 to 160 psi, 0 to 300 psi, and 0 to 600 psi. These ranges cover low to moderate pressure applications common in industrial processes. Other ranges may be available from the manufacturer but are not listed in the current inventory.

What is the connection size and type for BOURDON 437U gauges?

The BOURDON 437U series gauges have a 1/2 inch NPT male bottom connection. This is a standard industrial thread for pressure gauges, allowing direct mounting to process piping or manifolds. The bottom connection orientation is typical for panel-mount installations where the gauge is mounted flush with the panel face.

Can BOURDON pressure gauges be used for gas or liquid service?

Yes, BOURDON all-stainless steel pressure gauges are suitable for both gas and liquid service, provided the media is compatible with stainless steel wetted parts. They are commonly used for measuring pressure of air, water, oils, and many chemical fluids. However, they are not recommended for use with highly corrosive media that attack stainless steel, such as strong acids or chlorides, without additional protection.

Does 3G Electric supply BOURDON products?

Yes — 3G Electric (S) Pte. Ltd. supplies BOURDON products. We stock the BOURDON catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
