Is the Pressure Gauge 1000/1600 bar, EN 837, S1, MGS 18 (100/150 mm), Male Thread suitable for corrosive media and high vibration environments?

Yes. The Pressure Gauge 1000/1600 bar, EN 837, S1, MGS 18 (100/150 mm), Male Thread is suitable for corrosive media and high-vibration environments. Its stainless steel housing and high-grade AISI 316L internal components (Bourdon tube in AISI 316L for up to 1000 bar, duplex stainless steel for 1600 bar) provide strong corrosion resistance and compatibility with aggressive process media. The TIG-welded process connection ensures durable sealing under demanding conditions. Silicone oil filling damps pointer oscillations and reduces wear from pulsations and vibrations, protecting the movement and extending service life. With IP67 protection, an operating ambient range of −40°C to +65°C, process media temperature up to +65°C, and an integrated safety valve (S1), the gauge is engineered for reliable performance in chemical, petrochemical, power generation, and other harsh industrial environments.

Can the Pressure Gauge 1000/1600 bar, EN 837, S1, MGS 18 (100/150 mm), Male Thread be installed in high-temperature process lines above +65°C or require additional cooling/isolation?

Pressure Gauge 1000/1600 bar, EN 837, S1, MGS 18 (100/150 mm), Male Thread Format The gauge is specified for ambient temperatures from −40°C to +65°C and for process media up to +65°C. Therefore it is not rated for continuous installation in process lines with temperatures above +65°C without additional measures. For process media hotter than +65°C you should provide cooling or thermal isolation (e.g., cooling element, impulse line with cooling loop, syphon, or remote diaphragm seal) to ensure the gauge’s housing, internal components and silicone filling are kept within the specified temperature limits. Also verify that any added isolation does not impair accuracy, safety (S1 safety valve), or IP67 protection, and follow EN 837 installation guidelines for orientation and thermal protection.
