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).

Minimum operating temperature [°C]	-40

Pressure gauge of the MGS 18 series, 63 mm in diameter, compliant with EN 837-1, in a safe S2 version (without a front baffle), filled with silicone oil. Intended for measuring the pressure of gases and liquids of low viscosity and non-crystallizing, for use in the chemical and petrochemical industries, as well as in conventional power plants. Resistant to harsh operating conditions of the external environment and the process medium. It 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 in which pulsating pressures or mechanical vibrations occur. Filling the gauge with silicone oil helps to: reduce pointer fluctuations, reduce wear of the moving parts of the mechanism during pressure pulsations and vibrations. It also prevents condensation and the formation of a corrosive atmosphere inside the gauge, which could damage the internal parts. Connection: bottom or back centric. Dial diameter: 63 mm. Pressure range: 0÷1000 bar. Accuracy class: 1.6. Ambient temperature: from -40°C to +65°C. Medium temperature: up to +65°C maximum. Case material: stainless steel. Window: polycarbonate. Connection material: AISI 316L stainless steel. Bourdon tube: AISI 316L stainless steel. Movement: stainless steel. Filling: silicone oil. Safety class: S2. Protection rating: IP 67 (EN 60529/IEC 529).
