目前壓力開關已廣泛應用于各個行業，如液壓潤滑行業，低壓力保護控制，消防行業等等，那么想更好使用壓力開關就要明白有關問題，這一方面是值得了解的。
At present, pressure switches have been widely used in various industries, such as hydraulic lubrication industry, low pressure protection and control, fire protection industry, etc. if you want to better use pressure switches, you should understand the relevant problems, which is worth understanding.
1、壓力開關使用在什么環境
1. What environment is the pressure switch used in
有一些壓力開關需要能夠在特定的環境下正常使用，比如高水汽，高風塵等惡劣環境，所以對壓力開關的防水，防塵能力有所要求，客戶在選擇壓力開關的時候一定要根據使用的環境去檢查產品說明書上的防等級，一般情況下，如果對防水，防塵要求較高的話，等級為IPXX。
Some pressure switches need to be able to be used normally in specific environments, such as high water vapor, high dust and other harsh environments, so there are requirements for the waterproof and dustproof ability of the pressure switch. When selecting the pressure switch, the customer must check the anti grade on the product manual according to the environment of use. Generally, if the waterproof and dustproof requirements are high, the grade is ipxx.
2、壓力開關的輸出信號需要是模擬還是開關量
2. Whether the output signal of the pressure switch needs to be analog or switching value
壓力開關的種類很多，但是如何從眾多的壓力開關中選擇適用的呢？這里便有一個小竅門，通過判斷壓力開關的輸出信號的類型確定選擇哪種壓力開關。模擬輸出指的是如需要輸出4-20mA的模擬信號的話，應選用壓力變送器；如果輸出的是開關信號的話，別忘記要注意是選擇常開觸點，還是常閉觸點。
There are many kinds of pressure switches, but how to choose the applicable one from many pressure switches? Here is a trick to determine which pressure switch to choose by judging the type of output signal of the pressure switch. Analog output refers to the selection of pressure transmitter if it is necessary to output 4-20mA analog signal; If the output is a switch signal, don't forget to choose the normally open contact or the normally closed contact.
3、壓力開關需要怎樣的接口
3. What kind of interface does the pressure switch need
川消小編認為客戶一定要注意選擇合適的接口螺紋，避免沒有注意到這方面而導致另加連接件，然后和廠家退換貨，耽誤使用。
Chuanxiao Xiaobian believes that customers must pay attention to the selection of appropriate interface threads to avoid adding additional connectors without paying attention to this aspect, and then return and exchange goods with the manufacturer, delaying the use.
4、壓力開關使用的環境溫度及介質的溫度
4. Ambient temperature and medium temperature of pressure switch
壓力開關的內部材質材質直接決定了壓力開關的使用環境的溫度，溫度如果使用不當，會使壓力開關不動作或誤動作，比如壓力開關的死區直接影響了壓力開關的使用性能，從而直接影響用戶的使用。
The internal material of the pressure switch directly determines the temperature of the operating environment of the pressure switch. If the temperature is not used properly, the pressure switch will not act or misoperate. For example, the dead zone of the pressure switch directly affects the performance of the pressure switch, thus directly affecting the use of users.
5、壓力開關的大量程
5. Large range of pressure switch
壓力開關選擇的時候應該考慮到系統的大壓力，需要觸發開關動作的的壓力值點。舉個例子：當你的管道大壓力為1000kpa，在600kpa的時候，需要輸出開關信號。此時選擇耐壓在1000kpa以上，設定點能設到600kpa的壓力開關。
When selecting the pressure switch, we should consider the high pressure of the system and the pressure value point that needs to trigger the switch action. For example, when your pipeline pressure is 1000kPa and 600kpa, you need to output the switch signal. At this time, select a pressure switch whose withstand voltage is above 1000kPa and the set point can be set to 600kpa.
6、壓力開關的觸點容量
6. Contact capacity of pressure switch
這一點，非常重要的，在所有廠家的開關技術參數中都會有電氣的要求，這個參數取決于后繼電路的大電壓和大電流，如果選用不合適有擊穿的危險。另外了解一些壓力開關術語對于選購壓力開關還是很有必要的。
This is very important. There will be electrical requirements in the switch technical parameters of all manufacturers. This parameter depends on the high voltage and high current of the subsequent circuit. If it is not selected properly, there is a risk of breakdown. In addition, it is necessary to know some pressure switch terms for purchasing pressure switches.
This is the introduction of the matters related to the problem that you need to understand if you want to better use the pressure switch. I hope it will be helpful to you. If you want to know more about it, you can follow our website http://www.xintli.net consulting service
