Process pressure gauges

Nuova Fima MGS18 process pressure gauges are Bourdon tube pressure gauges with all-stainless-steel construction, available in nominal sizes of 100 and 150 mm (4" and 6"), designed to EN 837-1 with safety designation S1 to EN 837-2. They are intended for the chemical and petrochemical industries and conventional power plants, where they must withstand the most severe process and ambient conditions, operate with highly viscous and non-crystallising media and cope with high-frequency pulsating pressures. They cover ranges from 0…0.6 to 0…1600 bar and vacuum, with accuracy class 1 (0.6 optional up to 400 bar) and process fluid temperatures from -40 to +150 °C. The socket and seamless Bourdon tube are made of AISI 316L stainless steel (Duplex for the 1600 bar range), and TIG welding between case and socket strengthens the instrument. They are offered in standard (IP55), fillable or liquid-filled versions with glycerine or silicone oil (IP65/67): the damping fluid reduces pointer fluctuation and movement wear under vibration and pulsation, and protects the internals against condensation and corrosive atmospheres. Available with lower or back connection G 1/2 A or 1/2-14 NPT, front or back flange, ATEX II 2GD versions and a vented case for ambient temperatures down to -53 °C. They comply with the PED Directive 2014/68/EU, the ATEX Directive 2014/34/EU and EAC conformity. At Tecnovent we help you select the most suitable range, process connection and filling for your installation.
