| Function | Thermal Barrier and Instrument Protection |
A pressure gauge syphon is used to protect pressure gauges, transmitters and switches from direct exposure to high-temperature process media such as steam and hot fluids.
The syphon creates a thermal barrier by allowing a condensed liquid seal to form inside the pipe. This reduces heat transfer from the process line to the pressure instrument and helps maintain reliable measurement performance.
Our syphons are available in stainless steel and carbon steel materials and can be supplied with different configurations and end connections according to the installation requirements.
Industrial syphons are used wherever pressure instruments need protection from high-temperature steam, vapour or hot process media.
