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.

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. This version is
shown on separete data sheet available on request.
