They are built to resist the most severe operating conditions created by the ambient environment and the process medium. 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.
