Issues related to the selection of pressure gauges
Thread Content
I would like to ask the fellow sailors. The medium being measured is steam at 158 degrees Celsius, with a nominal pressure of PN25. Is it reasonable to use a stainless steel pressure gauge along with a condensation ring?
Also, there are many types of pressure gauges, such as diaphragm pressure gauges, membrane pressure gauges, electric contact pressure gauges, shock-resistant pressure gauges, and bellows pressure gauges. I’m not sure what situations these are generally used in Have you used big shrimp before?

Electric contact pressure gauges are used to measure the positive and negative pressures of gases and liquid media that do not cause corrosion to copper and copper alloys; they send out a signal when the pressure reaches a predetermined value, thereby activating the control circuit and achieving automatic alarm functionality.
The medium being measured is steam at 158 degrees Celsius, with a nominal pressure of PN25; I will use a stainless steel pressure gauge along with a condensation ring, and that should work fine. Electrical contact pressure gauges are used in applications where an alarm or interlock function is required. Shock-resistant pressure gauges are suitable for environments with high levels of vibration. Diaphragm gauges offer better precision for small measurement ranges. Diaphragm pressure gauges are used in situations where the material contains impurities that can cause blockages or crystallization
For this, you can refer to HG/T 20507-2000 Regulations for the Selection and Design of Automated Instruments.
Steam at 158°C, with a condensation coil – a regular pressure gauge is sufficient; there’s no need to use a stainless steel pressure gauge, as that would be too wasteful.
I suddenly realized today: is the difference between stainless steel pressure gauges, various special-purpose pressure gauges, and ordinary pressure gauges merely in their material? Previously, the difference in materials was assumed by default
The main difference lies in the material, with some differences in structure as well, such as diaphragm pressure gauges and shock-proof pressure gauges.
Okay, thank you. I hadn’t considered this issue before
Our steam is similar to what you described, at 160 degrees. PN10. A stainless steel pressure gauge is used, no problem
