Frequently Asked Questions
Q
What makes this pressure gauge suitable for use in hazardous or explosive environments?
This gauge is specifically engineered to eliminate ignition sources through its all-stainless-steel construction and excellent sealing design. It meets the requirements for use in explosive atmospheres, including areas with flammable gases, vapors, and combustible dust, making it a reliable choice for hazardous industrial zones.
Q
What is the connection size and thread type of this pressure gauge?
The gauge features a lower-mounted connection with a 1/2" NPT thread, which is a widely used standard in industrial piping systems across North America and internationally, ensuring easy integration into existing pipelines and equipment.
Q
What materials are used in the construction of this pressure gauge?
The key components — including the case, ring (cover), connection, Bourdon tube (sensing element), and movement — are all made from stainless steel. The pointer is aluminum alloy with a black finish, and the dial plate is white aluminum with black graduations, providing clear readability in various lighting conditions.
Q
Is this pressure gauge suitable for outdoor installation?
Yes. Thanks to its full stainless-steel construction and superior corrosion resistance, this gauge is well-suited for outdoor environments. It can withstand moisture, temperature fluctuations, and exposure to corrosive media, making it ideal for outdoor pipelines, drilling platforms, and open-air industrial facilities.
Q
Which industries typically use this type of explosion-proof pressure gauge?
This gauge is widely used across petrochemical plants, oil and gas extraction sites, pharmaceutical manufacturing facilities, coal and grain processing workshops, and gas production and distribution systems — essentially any industry where flammable gases, vapors, or combustible dust may be present.
Q
How does the Bourdon tube work and why is stainless steel used for it?
The Bourdon tube is a curved, hollow tube that straightens when internal pressure increases, converting pressure into mechanical movement that drives the pointer. Stainless steel is used for its high strength, excellent corrosion resistance, and ability to handle a wide range of media — including aggressive chemicals — without degrading, ensuring long-term measurement accuracy and reliability.
