Swagelok® Pressure Gauges, Ultrahigh-Purity and Clean Dry Air (PGU and PGC Series)
Swagelok® ultrahigh-purity and clean dry air pressure gauges use a Bourdon tube to reliably monitor positive system pressure and vacuum.
Request Pressure Gauge InformationSwagelok® PGU series ultrahigh-purity pressure gauges and Swagelok® PGC series clean dry air pressure gauges are designed for use in a wide range of applications, from bulk gas distribution to process tool applications. Their accuracy is in accordance with ASME B40.1. Dial sizes include:
- 50 mm (2 in.), ± 2% / 1% / 2% of span (ASME B40.1, Grade A, EN 837-1 Class 2.5, JIS B7505 Class 2.5)
- 40 mm (1 1/2 in.), ± 3% / 2% / 3% of span (ASME B40.1, Grade B, EN 837-1 Class 4, JIS B7505 Class 4)
- 28 mm (1 in.), ± 3% of span
PGU series gauges are ultrahigh-purity (UHP) “clean” for semiconductor gas applications in accordance with SEMI/SEMATECH, are cleaned and packaged in a class 100/10 cleanroom, and have 316L VAR end connections. PGC series gauges are assembled, cleaned, and packaged in a class 100 cleanroom and have 1/4 in. NPT end connections. Both series are purged with nitrogen and include protective cap over threaded connection.
