Description : 

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.
