Can the Pressure gauge 1000 bar 1.6 EN 837 (S2), MGS 18 (63 mm), male thread be installed in systems with pulsating pressures and strong vibrations?

Yes. The Pressure gauge 1000 bar 1.6 EN 837 (S2), MGS 18 (63 mm), male thread is suitable for systems with pulsating pressures and strong vibrations. It is a silicone-oil-filled, safe-design (S2) gauge compliant with EN 837-1. The oil fill damps pointer fluctuations and reduces wear on moving parts under pulsation and vibration, while preventing internal condensation and corrosive atmospheres. Construction uses stainless steel (AISI 316L) for connection, bourdon tube and mechanism, with polycarbonate window and IP67 protection, making it resistant to harsh environments and process media. Rated for ambient temperatures -40Â°C to +65Â°C and medium temperatures up to +65Â°C, it is explicitly intended for use in pumps, compressors, turbines, engines and other equipment where pulsating pressures or mechanical vibrations occur.

Is the Pressure gauge 1000 bar 1.6 EN 837 (S2), MGS 18 (63 mm), male thread suitable for outdoor use in corrosive marine environments?

Pressure gauge 1000 bar 1.6 EN 837 (S2), MGS 18 (63 mm), male thread is suitable for outdoor use in corrosive marine environments with reservations. Positives: stainless steel AISI 316L housing, connection, bourdon tube and mechanism offer strong corrosion resistance; silicone oil filling prevents internal condensation and corrosive atmosphere; IP67 rating ensures protection against immersion and dust; operating ambient range â40Â°C to +65Â°C suits marine climates. Caveats: polycarbonate window is less resistant to long-term UV exposure and some chemicals than glass; AISI 316L resists many marine corrosives but may suffer in highly chlorinated/brackish or splash zones long-term. Recommendation: for prolonged, direct seawater splash or very aggressive environments, consider added UV-resistant window, external protective housing or higher-grade alloys (Hastelloy/Monel) and regular inspection.

Does the Pressure gauge 1000 bar 1.6 EN 837 (S2), MGS 18 (63 mm), male thread require recalibration after silicone filling?

Pressure gauge 1000 bar 1.6 EN 837 (S2), MGS 18 (63 mm), male thread does not generally require recalibration solely because it has been silicone filled. Silicone filling is applied to stabilize the pointer under pulsation and vibration, reduce wear, and prevent internal condensation or corrosive atmospheres; it does not alter the instrumentâs metrological characteristics under normal conditions. Recalibration is recommended if any of the following occur: visible damage, significant mechanical shock, suspected accuracy drift, replacement or repair of pressure-containing components, exposure to overpressure beyond specified limits, or if regulatory/quality procedures require periodic recalibration intervals. Also recalibrate after any maintenance that affects the measuring system or when used outside specified ambient/medium temperature ranges (ambient â40Â°C to +65Â°C, medium up to +65Â°C).

MGS 18 series pressure gauge with a diameter of 63 mm compliant with EN837-1, in a safe design S2 (without front diaphragm), filled with silicone oil. Designed for measuring the pressure of gases and low-viscosity, non-crystallizing liquids, for use in the chemical and petrochemical industries, as well as for application in conventional power plants. Resistant to harsh environmental working conditions and process media. Can be used in drive units, pumps, water cleaning devices, presses, compressors, turbines, diesel engines, chemical, petrochemical, and refrigeration installations, as well as in machines and devices where pulsating pressures or mechanical vibrations occur. The filling of the gauge with silicone oil helps to: reduce indicator 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 pressure gauge, which could damage internal components. Connection: lower or rear central. Dial diameter: 63 mm. Pressure range: 0 to 1000 bar. Accuracy class: 1.6. Ambient temperature: from -40°C to +65°C. Medium temperature: up to +65°C maximum. Housing material: stainless steel. Window: polycarbonate. Connection material: stainless steel AISI 316L. Bourdon tube: stainless steel AISI 316L. Mechanism: stainless steel. Filling: silicone oil. Safety class: S2. Protection degree: IP 67 (EN 60529/IEC 529).
