Select the vacuum pressure switch according to the application scenario

Select the vacuum pressure switch according to the application scenario. You can refer to the following content:

Semiconductor manufacturing scenario

Semiconductor manufacturing has extremely high requirements for pressure control and needs to use vacuum pressure switches with high precision and high stability. For instance, the absolute pressure vacuum pressure switch of Hebei Lingguan Instrument & Meter Co., Ltd. features a reasonable structural design, high stability and fast response, which can meet the strict requirements for pressure control in semiconductor manufacturing scenarios. The ultra-clean vacuum pressure switch launched by Zhongke Jiumi for the semiconductor field has the advantages of high precision, high stability and ultra-high purity of materials. It can be applied to the transfer chamber (Load-Lock) to ensure pressure balance when transferring silicon wafers. It is used as a protective device for the flow and pressure of electronic devices in semiconductor production; Monitor multiple gas systems in the gas monitoring panel and output high and low pressure alarm signals.

Vacuum equipment scene

In vacuum equipment, vacuum pressure switches play a role in automatic control of pressure protection. When the vacuum pressure in the system exceeds the set point, the controller will automatically cut off the circuit and send a signal to ensure the normal operation of the system. For instance, some vacuum switches can be used to measure various vacuum degrees and are used in conjunction with various vacuum pumps to monitor pressure in real time in vacuum equipment. When the pressure is abnormal, they will promptly send signals to protect the equipment.

Industrial automatic control scenario

Industrial automatic control environments are involved in numerous industries, such as oil pipelines, water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil Wells, power, ships, machine tools, pipeline air supply, boiler negative pressure, etc. In these scenarios, vacuum pressure switches can be used for pressure control in metallurgy, chemical engineering, petroleum, steel, machinery, refrigeration equipment, freezing equipment, water pumps, low water level protection pressure control, as well as for gas, steam, water, oil and other liquid pressure equipment and other industrial equipment in power plants, cement, food, shipping and other industries, and in conjunction with actuators. Carry out pressure monitoring, alarm and interlock protection to achieve two-position automatic control. For example, the EA-VK series of pressure switches/pressure controller products are widely used in places that require pressure control in various industries such as petroleum, chemical engineering, metallurgy, power, sugar making, and pharmaceuticals, and play a role in pressure protection in the automatic control system.

Daily life scenes

Vacuum pressure switches are also applied in daily household appliances. Such as the start and stop control of coffee machines, the control of air pumps for small air compressors, and even the pressure detection of inflatable toy pumps, etc. It can replace traditional mechanical vacuum switches and pressure gauge switches, and be used in conjunction with vacuum pumps. It plays a role in situations that require high precision and rapid response, making pressure control simpler and more accurate.
