A. Product Overview
Baumer EH siphon is designed to protect pressure gauges from direct exposure to steam, hot vapours and high temperature process media. It works as a cooling barrier between the process line and the pressure gauge, helping improve gauge life and measurement reliability.
The Baumer EH siphon is available in coil type, pig tail type and U type construction. It is suitable for applications with maximum pressure rating up to 260 bar and working temperature up to 400 degree C. Process connection options include 1/4 inch, 3/8 inch and 1/2 inch BSP and NPT.
Wetted parts are available in AISI 304 SS, AISI 316 SS, AISI 316L SS and CS, making it suitable for different industrial pressure measurement applications.
B. Working Principle
The Baumer EH siphon works by creating a protective cooling loop between the hot process media and the pressure gauge. When used in steam or high temperature service, the siphon allows condensate to form inside the loop.
This condensate acts as a barrier and reduces the direct transfer of heat to the pressure gauge. As a result, the pressure gauge receives the process pressure but is protected from excessive temperature.
In coil type, pig tail type and U type designs, the siphon provides additional distance and cooling volume between the process connection and the gauge. This helps prevent overheating of the gauge internal components and supports stable pressure indication.
C. Why It Is Used
Baumer EH siphon is used to protect pressure gauges in high temperature and steam applications. Direct steam or hot media can damage the pressure gauge movement, bourdon tube, seals and internal components.
It is used because it helps reduce heat transfer, improves pressure gauge service life and supports safe pressure measurement. In boiler lines, steam pipelines, hot water systems and thermal process equipment, a siphon is commonly installed before the pressure gauge.
The Baumer EH siphon is also useful where process temperature is too high for direct mounting of a pressure gauge. Its different construction types and material options make it suitable for multiple industrial applications.
