Marsh Bellofram presents stainless steel pressure gauges, which are compliant with NACE MR-01-75. The gauges have been designed for increased life in severe and corrosive sour gas (H2S) conditions. All wetted parts comply with NACE MR0175 and adhere to minimum hardness requirements.
Their case is all-welded, which ensures higher strength. They are provided with liquid-fill to ensure significantly lower shock to the instrument grade parts. For added sturdiness and safety, a safety glass window is included. The gauges can be liquid-filled or dry. They feature an adjustable micrometer pointer. They are available in pressure ranges up to 20,000 psi.
The gauges are used in oil patch, refineries and rigs, control panels, offshore platforms, OEM and industrial process control, and all pressure regulation applications with presence of H2S (sour gases).
