A pressure siphon is a simple device to protect the pressure sensor from high temperature fluids such as steam. Siphons can also be used to reduce the damaging effects of rapid pressure changes.

Although the siphon is a relatively inexpensive device, it can be installed to install a low temperature sensor in high temperature processes.

A typical siphon can be made of carbon steel material that is suitable for pressures up to 48 bar and temperatures up to 230 ° C.

Another common material in the construction of the siphon is stainless steel, which usually withstands higher pressures and temperatures. Use stainless steel siphon up to 400 ° C and 160 bar pressure.

Advantages of installing a siphon with a pressure gauge
Improve performance and extend the life of pressure gauges
Reduce the destructive effects of temperature
Sudden decrease in pressure pulses
Possibility of installing low temperature sensor with siphon for high temperature processes
