目前压力开关已广泛应用于各个行业，如液压润滑行业，低压力保护控制，消防行业等等，那么想更好使用压力开关就要明白有关问题，这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、压力开关使用在什么环境
1. What environment is the pressure switch used in
有一些压力开关需要能够在特定的环境下正常使用，比如高水汽，高风尘等恶劣环境，所以对压力开关的防水，防尘能力有所要求，客户在选择压力开关的时候一定要根据使用的环境去检查产品说明书上的防等级，一般情况下，如果对防水，防尘要求较高的话，等级为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、压力开关的输出信号需要是模拟还是开关量
2. Whether the output signal of the pressure switch needs to be analog or switching value
压力开关的种类很多，但是如何从众多的压力开关中选择适用的呢？这里便有一个小窍门，通过判断压力开关的输出信号的类型确定选择哪种压力开关。模拟输出指的是如需要输出4-20mA的模拟信号的话，应选用压力变送器；如果输出的是开关信号的话，别忘记要注意是选择常开触点，还是常闭触点。
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、压力开关需要怎样的接口
3. What kind of interface does the pressure switch need
川消小编认为客户一定要注意选择合适的接口螺纹，避免没有注意到这方面而导致另加连接件，然后和厂家退换货，耽误使用。
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、压力开关使用的环境温度及介质的温度
4. Ambient temperature and medium temperature of pressure switch
压力开关的内部材质材质直接决定了压力开关的使用环境的温度，温度如果使用不当，会使压力开关不动作或误动作，比如压力开关的死区直接影响了压力开关的使用性能，从而直接影响用户的使用。
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、压力开关的大量程
5. Large range of pressure switch
压力开关选择的时候应该考虑到系统的大压力，需要触发开关动作的的压力值点。举个例子：当你的管道大压力为1000kpa，在600kpa的时候，需要输出开关信号。此时选择耐压在1000kpa以上，设定点能设到600kpa的压力开关。
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、压力开关的触点容量
6. Contact capacity of pressure switch
这一点，非常重要的，在所有厂家的开关技术参数中都会有电气的要求，这个参数取决于后继电路的大电压和大电流，如果选用不合适有击穿的危险。另外了解一些压力开关术语对于选购压力开关还是很有必要的。
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.cx-fire.com consulting service
