Can the Pressure gauge 2500 Ã· 4000 bar 1.0 safe (S3) with HP process connection, MGS 22 (100, 150 mm) be used with abrasive or corrosive gas media without additional protective measures?

No . the Pressure gauge 2500 Ã· 4000 bar 1.0 safe (S3) with HP process connection, MGS 22 (100, 150 mm) is not suitable for abrasive or strongly corrosive gas media without additional protective measures. Although the gauge features stainless steel AISI 316L housing and duplex stainless steel Bourdon tube, silicone oil filling, IP67 protection, and an S3 safety design compliant with DIN 16001, its specifications limit use to gases and lowâviscosity, nonâcrystallizing liquids and list a medium temperature up to +65Â°C. Abrasive gases can erode the pressure connection and sensing element; corrosive gases can attack wetted parts and degrade seals and internal components over time. For abrasive or corrosive media, use additional protective measures such as isolation barriers (diaphragm seals with compatible fill fluid), protective filters or scrubbers upstream, special corrosionâresistant wetted materials beyond AISI 316L where required, and regular inspection/maintenance. Consult manufacturer for material compatibility and approved isolation solutions before application.

Is the Pressure gauge 2500 Ã· 4000 bar 1.0 safe (S3) with HP process connection, MGS 22 (100, 150 mm) suitable for abrasive or corrosive liquids without extra protection?

Pressure gauge 2500 Ã· 4000 bar 1.0 safe (S3) with HP process connection, MGS 22 (100, 150 mm) Format: No - it is designed for gases and lowâviscosity, nonâcrystallizing liquids and is mainly intended for highâpressure water applications. While silicone oil filling reduces condensation, vibration and internal corrosion risk, the instrument is not specified for abrasive or chemically corrosive liquids without additional external protection or special internal materials/coatings. For abrasive or corrosive media use, consult manufacturer for suitable wettedâpart materials, protective barriers or diaphragm seals.

MGS22 series manometer, filled with silicone oil, for high-pressure applications, for measuring the pressure of gases and low-viscosity, non-crystallizing liquids, in a safe design S3 (EN 837-2), with special HP connections. Complies with the latest standard for ultra-high-pressure manometers DIN 16001. It features a solid front baffle wall and a blow-out back element, protecting the operator in case of pressure element (Bourdon tube) failure. The process connection is welded (TIG) to the housing, which strengthens the manometer and ensures better housing tightness. Mainly used in cutting or cleaning technologies of various materials using high-pressure water jets, e.g., in water cutting machines, pumps, and water turbines. The silicone oil filling of the manometer helps reduce pointer fluctuations, decrease wear on moving parts of the mechanism under pressure pulsations and vibrations. Additionally, it prevents condensation and the formation of a corrosive atmosphere inside the manometer, which could damage internal components. Upon request, MGS22 manometers are available for 5000 and 6000 bar (150 mm), accuracy class 1.6 in accordance with DIN 16001. Connection: bottom. Dial diameter: 100 mm, 150 mm. Pressure ranges: 0 to 2500 bar, 0 to 3000 bar, 0 to 4000 bar. Accuracy class: 1.0. Ambient temperature: from -40°C to +65°C. Medium temperature: maximum up to +65°C. Housing material: stainless steel. Window: laminated safety glass. Connection material: stainless steel AISI 316L. Bourdon tube: duplex stainless steel. Mechanism: stainless steel. Filling: silicone oil. Safety class: S3. Protection degree: IP 67 (IEC 529).
