Pressure gauge Capillary
Thread Content
Some pressure gauge pressure conduits are ordinary tubes, while others use capillaries – what is the difference? Where are pressure gauges with capillaries used? I seek advice from experts. Thank you all first.

This choice mainly depends on the medium properties!
1. A pressure gauge with a flat diaphragm and capillary transmission structure is used when using pressure tapping tubes, and the medium can cause blockages or solidification in the tubes. 2. Such a pressure gauge is employed when using pressure tapping tubes and the differential pressure gauge cannot ensure that one end of the tube is completely filled or completely empty
The pressure lead is used to measure the gas phase pressure or to shift the pressure; the capillary is much simpler – it can be installed easily, and once installed, just remember to reset it.
Do you mean the diaphragm flange with filling fluid by your so-called capillary? If that is the case, capillaries are used for corroding viscous, toxic, or solid-containing media, with the main purpose being to prevent the leakage of such media or the blockage of pressure transfer tubes.
