bourdon tube pressure gauges all stainless steel construction DS 4”, 6” (100-150mm) MGS18 PED 97/23/CE ATEX 94/9/CE ME 48 Gost R Pattern Approval Chinese Pattern Approval These instruments are designed for food, processing, pharmaceutical, petrochemical industries and for conventional and nuclear power plants. They are built to resist to the most severe conditions created by the process medium and by the environment and for those fluids, which have high viscosity and do not crystallize. The quality of the materials used to build the sensible element allows their use with high frequency pulsating pressures. The TIG welding between the case and the process socket, strengthens the instrument and assures better containment of dampening fluid. The advantages of filling the case of the instrument with a dampening fluid are: reduced pointer fluctuation, reduced wear of rotating parts of the movement when pulsant vibrations and pulsations occur. Moreover condensation and corrosive atmospheres which could damage the internal parts are prevented. Standard Model Fillable Model Design: EN837-1. Safety designation: S1 as per EN 837-2. Ranges: from 0...15 to 0...30000 psi (from 0...0,6 to 0...1600 bar or equivalent units). Accuracy class: 1 as per EN 837-1. Ambient temperature: -13...+149 °F (-25...+65 °C).

INSTRUMENTS FOR OXYGEN To suit safety criteria of standard EN837-1/2, the pressure gauges for oxigen service must be solid-front type (with baffle wall and safety bursting back). Pressure gauges suitable for this service are detailed on MGS20 DS 4”, 6” (100-150 mm) sheet. For use in potentially explosive atmospheres, instruments must be designed in conformity to ATEX 94/9/CE.
