壓力開關的抗干擾措施
在之前如何有效防止壓力開關受外界干擾的文章中，小編為大家介紹了三種抗干擾措施，其中一種是采用線纜屏蔽措施，今天小編在這里為大家介紹壓力開關屏蔽線纜的一些相關知識。
一、何謂屏蔽線纜
所謂屏蔽線纜是指在壓力開關線纜外面包裹一層屏蔽層，該屏蔽層一般都是由導電布或者鋁網(wǎng)等構成，將干擾信號導入到地面，使干擾得到有效的屏蔽，進而保證了壓力開關信號傳輸?shù)恼�。其主要是將電磁波、電磁場等干擾屏蔽，適用于不同的種類可以用于不同的工業(yè)場合中需要屏蔽電磁干擾的固定場合。
二、使用線纜屏蔽注意事項：
1.壓力開關屏蔽線纜的工作溫度盡量不超過70℃。
2.對于自帶屏蔽結構的電纜，要選擇大于壓力開關新蘭外徑的十倍。
