Overview
The pressure surge reducer protects the pressure gage against
damage, premature wear and tear and inaccurate/fluctuating in-
dications.
■
Application
The pressure reducer is used when pulsations occur in the mea-
sured medium (e.g. in slow-running vapor engines, piston
pumps and compressors), or if drastic fluctuations are likely to
occur in the measured medium (e.g. in hydraulic presses and
tensile testing machines).
■
Design
• Enclosure made of brass or stainless steel
• Adjustable nozzle
• Sleeve for connection to the measuring instrument
• Pin for connection to supply lead
