- Protection of pressure gauges against sudden variations in pressure (pressure peaks, pressure surges, pulsating regime, etc.).

A damper A201 protects the pressure measuring instrument against undesirable effects of pulsating regime. It includes an adjustable needle which narrows the pressure channel, to adjust according the operating conditions. Well adjusted on site, it considerably increases the service life of pressure gauges in conditions of use where the pressure varies abruptly such as on compressors, pumps, while preserving precision.

Note: In the case of mechanical vibrations, the use of a pressure gauge oil filled is
required.
