Siphon Tube For Pressure Gauge

Siphon Tube For Pressure Gauge

Siphon Tubes protect your pressure instruments, gauges, switches and transmitters from high-temperature process fluids. Siphon Tubes are used to protect those directly coming in contact with high-temperature process fluids or vapors. These reduce steam or other process media temperature prior to entering into these instruments. Syphons are manufactured to stringent quality control program and standards which assure the highest quality available in the industry.

Siphon Tube WIKA

Syphons per DIN 16282 U-form, form B, and trumpet form, form D, have a welding connection for the pressure tapping on the process side and a threaded connection on the instrument side. In the industrial standard versions, threaded connections are also available for the pressure tapping on the process side. U-form syphons are intended for horizontal pressure tapping; trumpet-form syphons are intended for vertical pressure tapping. Inside the syphon, condensate is collected, which prevents the ingress of hot media into the measuring instrument. We recommend filling the siphon with a cooling separating liquid before commissioning the pressure line.

Siphon Tube Applications

• Syphons protect the pressure measuring instruments from pulsations in the medium and from excessive heating
• The cooling element for fluids, gases, and vapors in pressure measurement
• For direct mounting to the pressure connection of the pressure measuring instrument or to the shut-off device (stopcock or valve) mounted underneath
