These instruments are designed for petrochemical industry. They are built to resist to the most severe conditions created by H2S and by the environment. 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 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 pulsant vibrations and pulsations occur. Moreover condensation and corrosive atmospheres which could damage the internal
– All stainless steel pressure gauge, NACE MR 01.75, case diameter 100 and 150 mm
– Solid-front execution also available (the safety construction consists of a solid separating wall placed between the scale and the elastic element, and a blow out back which is released from the case whenever an internal pressure, due to leak, is created or the elastic element is broken)
