小型壓力開關的選型需知
小型壓力開關憑其結構緊湊，外觀精致，方便攜帶等優越性能，在市場上越來越受到客戶們的青睞，本篇文章就教大家一些小型壓力開關的選型需知。
需知參數1：量程范圍。
量程范圍即是指要測量的最小測量值和最大測量值中間的范圍。選型之前需要清楚最大測量值，然后根據比最大測量值還大1.5倍的數值來選擇，否則容易造成超負荷工作損壞小型壓力開關。
需知參數2：被測介質。
隨著被測介質的性質不同，對小型壓力開關的要求也在改變，如被測介質的腐蝕性，則應挑選對應能抗腐蝕的小型壓力開關。
需知參數3：測量精度。
小型壓力開關的精度越高越好，如對精度要求較高，應選擇0.2%，或0.1%的測量精度。
需知參數4：接口尺寸。
客戶應根據工作現場的使用條件，量出相應的接口尺寸，根據尺寸選擇相應的小型壓力開關。
