Pressure gauges

All stainless steel construction PBX100, PBX150 (1.18)

These instruments are designed for use in food, beverage, pharmaceutical, cryogenics, chemical and petrochemical processing industries, and in conventional and nuclear power plants. They are built to resist the most severe operating conditions created by the ambient environment and the process medium. An Argonarc welded case/socket strengthen the whole construction. A leak tight fit is ensured if the instrument is filled with a dampening fluid to prevent damage due to vibration. 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, avoidance of contamination to the internal parts by corrosive atmosphere gases, avoidance of condensation of the front window lens, ensuring the instruments are suitable for use on equipment with very high pulsation and severe vibration.
