Durable and Reliable Differential Pressure Measurement

The PTGB Series Differential Pressure Gage is designed for industrial environments, featuring a sturdy machined aluminum body with powder-coated or matte finish. Its acrylic window and brass wetted parts provide chemical resistance for compatible gases and liquids. The analog display, paired with a high-contrast dial and precision pointer, ensures readings are easily visible and interpreted swiftly. This gage suits demanding applications such as filter monitoring and process control, consistently delivering accurate and reliable results.

User-Friendly Installation and Maintenance

Equipped with a panel mount design and a convenient mounting bracket, the PTGB gage allows for straightforward installation. The external zero adjustment screw supports ongoing accuracy without dismantling the device. Minimal maintenance is required, thanks to rugged construction and resistant materials, allowing continuous operation in challenging settings. Both the instruction manual and clear scale range facilitate quick setup and routine checks.

FAQs of Series PTGB Differential Pressure Piston-Type Gage:

Q: How does the PTGB Differential Pressure Piston-Type Gage work?

A: This gage operates using a piston-type sensing element, which moves in response to changes between upstream and downstream pressures. The displacement of the piston is mechanically linked to an analog pointer, providing a direct differential pressure reading on the scale.

Q: What are the typical applications for this gage?

A: The PTGB gage is widely used in filter monitoring, flow measurement, and liquid or gas level indication within industrial settings. Its robust build and compatibility with non-aggressive gases and liquids make it well-suited for these applications.

Q: When should I perform zero adjustment on the gage?

A: Zero adjustment is recommended during initial installation and periodically throughout use, especially after significant temperature shifts or mechanical impacts, to ensure measurement accuracy. The external screw makes this process simple and tool-assisted without having to open the housing.

Q: Where is the connection port located on the gage?

A: The gage features a back-mounted 1/8 NPT connection, facilitating easy and secure integration into panel systems or equipment enclosures.

Q: What materials are used for wetted and sealed parts?

A: Wetted parts are made from brass, while the seals are constructed of nitrile rubber (NBR). The housing itself is machined from aluminum and finished for corrosion resistance, contributing to both longevity and reliability in industrial environments.

Q: How quickly does the gage respond to pressure changes?

A: It offers a rapid response time of under one second, enabling timely detection of pressure fluctuations and supporting effective process monitoring and safety.

Q: What are the main benefits of using the PTGB gage?

A: Key advantages include its high accuracy (2% F.S.), rugged construction, easy installation with included bracket, straightforward maintenance, and suitability for a range of industrial applications involving compatible gases and liquids.
