What are dampeners and siphon pipes used for?
Dampeners are used to minimize the effects of pulsations or sudden surges on equipment such as pressure gauges. They restrict the pathway by means of a throttling mechanism similar to that of a needle valve. Siphon pipes are filled with fluid to prevent high temperature fluids from coming into direct contact with pressure gauges and transmitters, while at the same time preventing the radiant transmission of heat from the surface to the instrumentation.
