Dial Pressure Gauges

Yes, industrial-grade dial pressure gauges are designed for high accuracy. Their precision depends on the specific model and its design, often adhering to standards like ASME B40.1. The accuracy is typically expressed as a percentage of the full-scale range. For demanding applications in oil and gas, selecting a gauge with the appropriate accuracy grade is crucial for reliable process control and safety.

Most dial pressure gauges operate using a Bourdon tube, a C-shaped, sealed tube that flexes when pressure is applied. As system pressure increases, the tube attempts to straighten. This movement is transferred through a system of gears and levers to the pointer on the dial, indicating the pressure level. This simple, mechanical design is robust and reliable for industrial environments.

Our industrial pressure gauges are specifically engineered for harsh and demanding environments. With heavy-duty, one-piece case construction, they are ideal for the rigors of upstream, midstream, and downstream oil and gas operations. They are built to withstand vibration, pulsation, and corrosive atmospheres, ensuring long-term reliability in challenging field and plant conditions.

Absolutely. To protect the instrument's internal components from corrosive, viscous, or high-temperature media, our pressure gauges are compatible with diaphragm seals. A diaphragm seal provides a protective barrier between the process fluid and the gauge itself, ensuring accurate readings and significantly extending the service life of the instrument in aggressive applications.

We offer a range of accessories to enhance performance and protection. These include needle valves for isolating the gauge from the process, diaphragm seals for protection against corrosive media, and thermowells for temperature measurement in pressurized systems. These accessories allow you to create a complete and robust instrumentation setup tailored to your specific operational needs.

Selecting the right gauge involves considering the pressure range, process media, operating temperature, and required accuracy. For oil and gas applications, durability and compatibility with accessories like diaphragm seals are also key factors. Our technical support team can assist you in evaluating your requirements to recommend the most suitable gauge for optimal performance and safety.
