A pressure gauge siphon is a simple device used to protect a pressure sensor from high temperature environments such as steam. It can also be used to reduce the potential damaging effects of rapid pressure changes. These low-cost devices allow system builders to use a pressure sensor with a very low temperature range in high temperature applications. Gauges are used to protect the pressure pressure from the effects of hot pressures such as steam, as well as to reduce the effect of rapid pressure increases. The siphon allows condensate to form and collect inside the siphon, preventing the direct entry of hot liquids (hot vapors, not just steam). It is also used as a freezing protector when using suitable filler fluids. For more information, read the article Pressure Gauge.
Types of pressure gauge siphons:
- Siphon coil
- U-shaped siphon
- Compact siphon with pressure gauge
- Siphon 90 degrees
Siphon coil
Siphon coils are commonly used for vertical installations.
U-shaped siphon
U-shaped siphons are commonly used for horizontal installations.
Siphon 90 degrees
A 90-degree siphon is used, while gauges are not required due to service conditions. Straight pipe is used for vertical installations. 90 degree elbow is used for horizontal installations.
Compact siphon with gauge
Compact gauge components can be used instead of siphon coils for vertical installations. Compact siphon with gauge is available as standard as well as Snubber Type integral.
