Swagelok® Pressure Gauges, General Purpose Gauge with ECE R110 Approval (PGN Series)
Obtain precise pressure measurements for compressed natural gas (CNG) vehicle applications with gauges certified to ECE R110 standards.
Request Pressure Gauge InformationSwagelok® PGN series gauges are general-purpose pressure gauges certified to ECE R110 standards for use in compressed natural gas (CNG) vehicles. Featuring a polycarbonate lens for enhanced protection, these natural gas pressure gauges ensure durability in demanding environments.
Available in 50 mm (2 in.) and 63 mm (2 1/2 in.) dial sizes, they offer a measurement range of 0 to 40 MPa (400 bar, 6000 psi) with an orifice size of 0.023 in. (0.58 mm).
Options include a brass end connection with a Bourdon tube for the 50 mm (2 in.) gauge, transducer output for the 50 mm model with brass end connections, and calibration and material certifications for precise application needs.
