Ametek 046987 Pressure Gauge 15PSI 1/4″ ANPT

Sure! Here’s a more detailed look at the Ametek 046987 Pressure Gauge and its possible applications:

Key Features and Specifications:

1. Pressure Range:

   • The 15 PSI range indicates that this gauge is designed to measure low-pressure systems, typically for systems where the pressure doesn’t exceed 15 PSI. This makes it suitable for delicate or low-pressure applications.

2. Accuracy:

   • Ametek gauges are known for their accuracy and reliability, with typical tolerances being ±1.6% of full scale or better, but this can vary depending on the specific model and calibration.

3. Connection Type:

   • The 1/4″ NPT (National Pipe Thread) connection is a standard threaded fitting, often used for connecting pressure gauges to a wide variety of piping or equipment. The NPT threading ensures a secure seal when installed, minimizing the risk of leaks.

4. Dial Size:

   • The exact dial size (typically expressed in inches, like 2″, 2.5″, 3″, etc.) isn’t specified in your inquiry, but Ametek generally offers gauges with varying dial sizes. A larger dial size typically provides greater visibility and easier reading.

5. Material Construction:

   • These gauges often feature a stainless steel case and brass internals, providing both durability and resistance to corrosion. The wetted parts (the components in direct contact with the fluid being measured) are usually made from stainless steel, which is important for preventing wear and corrosion over time.

6. Movement Type:

   • Most Ametek pressure gauges use a bourdon tube movement, which is a type of mechanical system that deforms under pressure and moves the needle on the dial to indicate the pressure.

7. Operating Environment:

   • This gauge is typically designed for use in a non-corrosive, clean environment. If you are using it with liquids or gases, they should be compatible with the materials used in the construction of the gauge.

Common Applications:

• HVAC Systems: Monitoring low-pressure refrigerant systems or air handling units.
• Water Systems: Used to monitor the pressure in water or fluid circulation systems, such as cooling systems or filtration units.
• Pneumatic Systems: Monitoring the pressure of compressed air or gas in systems like pneumatic actuators or pressure regulators.
• Laboratories: Used in experiments or equipment that require precise and low-pressure measurements.
• Hydraulic Systems (Low Pressure): Used in systems where low pressure is involved, such as hydraulic test equipment.

Installation and Use:

• Mounting: Typically, these gauges are installed directly onto a threaded pipe or fitting. The 1/4″ NPT fitting allows easy installation on most standard piping systems.
• Orientation: It’s important to mount the gauge in a position where the dial is easily readable. Some gauges are designed for panel mounting, while others might be surface-mounted or have a rear connection for direct mounting.
• Zero Adjustment: Many mechanical pressure gauges come with a zero adjustment screw that allows users to calibrate the needle to zero when there is no pressure.
