Diaphragm pressure gauges, also known as micromanometers, as the name suggests, are specialized...Diaphragm Pressure GaugeThe device can measure low-pressure levels, as well as liquids or gases that are non-explosive, non-crystallizing, and non-caking. Therefore, it is widely used in boiler ventilation, gas pipelines, combustion units, and other similar equipment. Stainless steelDiaphragm Pressure GaugeThe pressure gauge and housing are both made of stainless steel. They are applied in processes with high corrosion resistance requirements for measuring the micro-pressure and negative pressure of various gas mediums. Where does the main difference between the diaphragm pressure gauge and the ordinary pressure gauge lie?
Diaphragm Pressure GaugeThe range of general pressure measurements is not sufficient. Standard pressure gauges cannot measure properties like water and oil, nor can they measure gases such as oxygen and hydrogen for oxidation. Membrane box pressure gauges are tested using oxidation measurement ranges, which can help determine the differences between membrane box pressure gauges and standard pressure gauges.
However,Diaphragm Pressure GaugeThe measurement is oxidizing; these media are exposed to air, and they change with every moment of contact with the air. This is similar to the variable measured by the diaphragm pressure gauge. Therefore, the diaphragm pressure gauge measurement requires a strict safety factor during measurement, and also demands stringent hygiene conditions.
1. Measure the characteristics of the medium
General pressure gauges are commonly used to measure the pressure of non-oxidized liquids and gases.Diaphragm Pressure GaugeOur sensors can measure gases or liquids with oxidizing properties. However, when measuring oxidizing substances, it is essential to know the specific type of oxidizing property and select the appropriate diaphragm material based on its oxidizing characteristics to achieve effective measurement.
2. Different measurement processes for health and safety levels
General pressure gauges are commonly used for measuring media with low hygiene requirements, as the gas or liquid being measured does not move outside the pressure gauge during the pressure measurement process. However, for food applications, a high-quality diaphragm pressure gauge must be used. Since diaphragm pressure gauges employ an indirect measurement method, they deform under the influence of test pressure, squeezing the sealing liquid to create a certain pressure, which is then transmitted to the gauge and displayed as the test pressure value. Therefore, the gauge does not have direct contact with the test medium, ensuring a higher level of hygiene and safety.
This highlights the primary distinction between diaphragm pressure gauges and standard pressure gauges. Therefore, for pressure measurements where oxidation properties are present and high hygiene standards are required, diaphragm pressure gauges must be used to ensure more accurate pressure readings and meet hygiene safety requirements.
