ARA Pulsation dampener Main Features Improves readability of pressure Option: NACE conform gauges Reduces the effect of pulsations Max. 600 bar Max. 250 °C Applications Oil & Gas / Chemical Water & Waste water Energy Machinery Description Technical data Pulsation dampeners are used to protect pressure measurement instruments from ram effects and fluid pulses. They can be adjusted even during use. In use, the ARA 06 has a greater operating adjustment range and can be used with manometers as well as with transmitters. Further, the ARA 06 is suitable for higher pressure and temperature ranges. The ARA 10 must be screwed down fully then slightly unscrewed (1/8 turn maximum) to adjust the damping. Its adjustment range is thus smaller than that of the ARA 06. It cannot be used with transducers.
