防爆壓力開關的防爆概念
要想使用防爆壓力開關，就必須要清楚防爆壓力開關的防爆概念，之后才能根據實際需要挑選符合要求的防爆壓力開關，下面就跟著小編一起了解防爆概念吧。
如果工作場所是可能發生爆炸的氣體環境，如含有可燃性氣體、粉塵環境等場合，那就需要使用防爆壓力開關了，因為這些物質在大氣條件下，很容易與空氣中的氧氣結合發生爆炸。這種爆炸性氣體環境又可分為危險區域和非危險區域。危險區域是指已經含有和即將含有大量爆炸性氣體的環境，這種屬于高危區域需要第一時間使用防護等級高的防爆壓力開關；另一種則是指爆炸性氣體不會大量出現，也不會對工業生產造成威脅的場所，不過為了安全起見，這種場所最好也使用防爆壓力開關，可以相對的使用防護等級較低的防爆壓力開關。
防爆壓力開關的重要性在上述分析中已經很明顯了，所以用戶在選擇壓力開關時，應慎重考慮是否該選擇防爆型的壓力開關。
