MGS40 DN100-150 Bourdon Tube Solid Front Pressure Gauge
Brand: Nuova FimaThese instruments are built in conformity with the construction and safety specifications of EN 837-1/S3 e ASME B40.1.
In case of leaks or break of the elastic element, the operator is protected by a solid separating wall placed on the front of the instrument and by the blow out back.
They are usually used in the petrochemical and natural gas industry; they are built to resist to the most severe conditions created by H2S, by the environment and for those fluids, which have high viscosity and do not crystallize.
The TIG welding between the case and the process socket, strengthens the instrument and assures a better tight in case 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 pulsing vibrations and pulsations occur.
Moreover condensation and corrosive atmospheres which could damage the internal parts.
