壓力開關的防護措施
1.當壓力開關要測量帶黏度、易結晶及腐蝕性介質時，使用單位要加裝隔離裝置，盡量使壓力開關與介質隔離。
2.若壓力開關日后要測的壓力中存在壓力波動的情況，那使用單位要記得加裝緩沖裝置，避免壓力的劇增或陡降，導致壓力開關的敏感元件受損。
3.如果壓力開關日后的使用環(huán)境是振動的管道中，為了確保壓力開關的正常測量，應采取雙重防護措施：加裝固定裝置或減振裝置。
4.當壓力開關被測介質的溫度較高或者較低時，使用單位應針對不同的情況采取相對應的防護措施。
5.針對特殊用途的壓力開關應采取特殊的防護，如智能壓力開關要重點保護顯示屏；防爆壓力開關則要著重注意它的密封與防爆性能。
