Supported Applications
The Omega PGC Series consists of commercial-grade Type C pressure gauges designed for industrial applications. Documented uses include installation on pumps, portable compressors, and industrial machinery. The series is also specified for hydraulic and pneumatic systems, instrumentation, and pressurized vessels.
Operating Conditions & Performance
The PGC Series features an OMEGA® spring-suspended movement suspended between two springs to reduce wearing parts and provide resistance to mechanical shock and vibration. Movement parts are ultrasonically cleaned and lubricated with silicone oil for long cycle life.
- Accuracy: 3-2-3% (3% over first and last 10% of range, 2% over remainder)
- Ambient Temperature Limit: 66°C (150°F) maximum
- Pressure Ranges: Vacuum to 600 psi. Specific standard ranges include 30/0 inHg vac, compound vacuum-to-pressure spans such as 30 inHg vac to 15 psi through 30 inHg vac to 100 psi, and positive pressure from 0 to 15 psi up to 0 to 600 psi.
Configuration Options
The series is configured by dial size, connection orientation, and range code. The construction includes a painted steel case with a polycarbonate plastic window. Wetted materials consist of a bronze Bourdon tube and brass process connections.
- Dial Sizes: 50.8 mm (2") and 63.5 mm (2½").
- Process Connection: Brass ¼ NPT for all variants.
- Connection Orientation: Lower or Back mount options are available depending on the model code suffix.
- Ranges: Standard ranges cover vacuum, compound (vacuum to pressure), and positive pressure up to 600 psi. Other standard ranges may be available via Omega's online catalog.
Key Product Differences
The PGC Series model number follows the format PGC-<DIAL SIZE><CONNECTION>-<RANGE CODE>. The dial size is indicated by "20" for 50.8 mm (2") and "25" for 63.5 mm (2½"). Connection orientation is denoted by the letter following the dial size: "L" indicates a Lower connection, while "B" indicates a Back connection.
Dimensions vary by dial size. The 50.8 mm model has an overall width of 53 mm (2 1/64 in) and weighs approximately 4½ oz. The 63.5 mm model measures 69 mm (2 3/32 in) wide and weighs approximately 6 oz.
