Dwyer Instruments LPG4-D8122N Pressure Gage
The Dwyer Instruments LPG4-D8122N is a professional-grade low pressure gage designed for precision monitoring in commercial HVAC and industrial piping systems. Engineered with beryllium copper diaphragm sensing elements and brass wetted parts, this 2-1/2 inch gage provides a reliable 0 to 15" w.c. range with a rated accuracy of ±1.5% full scale. The 1/4" male NPT bottom connection ensures seamless integration into standard manifolds and gas lines. Built for durability in demanding environments, the drawn steel housing features a black finish and is rated for NEMA 3 (IP54) protection, making it suitable for locations where dust or splashing water may be present. This capsule-type pressure gage is essential for contractors verifying manifold pressure, calibrating burners, or monitoring leak detection systems where low-level fluctuations are critical for equipment safety and performance.
Key Benefits:
- High Sensitivity: The beryllium copper capsule allows for precise measurement of inches of water column without the drift common in lower-quality movements.
- Rugged Construction: NEMA 3 enclosure and steel case provide professional field durability for mechanical rooms and rooftops.
- Clear Legibility: The 2-1/2" (63 mm) face allows for rapid pressure verification from a distance during system startup and commissioning.
- Standard Compatibility: The 1/4" NPT connection fits most standard air or gas system ports without the need for additional adapters.
Common Questions:
Can this gage be used for liquid media?
No, this unit is designed for use only with compatible gases and air. The internal diaphragm mechanism is sensitive and will be damaged if exposed to liquids.
Is this suitable for outdoor installation?
The NEMA 3 rating provides protection against rain and sleet; however, it should be protected from extreme impacts and corrosive atmospheres to maintain calibration accuracy.
What is the overpressure limit for this model?
To prevent permanent deformation of the beryllium copper element, do not exceed the full-scale range during testing or purging cycles.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
