使用壓力開關需明確的幾項因素
壓力開關在使用時，需要明確如下幾個因素
1.明確壓力開關的精度：根據現場的測量要求，保證所選壓力開關的精度可以達到實際被測壓力允許的最高精度就可以，只需根據實際情況選擇，不需要選擇過高精度的壓力開關。
2.明確壓力開關的被測介質：明確被測介質主要是明確壓力開關被測介質的性質如何，物理性質和化學性質都要考慮到，如介質是氣體還是液體，介質是否具有腐蝕性，是否帶黏度等等。
3.明確壓力開關的測量范圍：為了保證壓力開關日后測量結果的準確性，它的最大壓力不可以超過壓力開關量程的2/3，而最小壓力則不可以小于量程的1/3，如果在測量過程中會不定時的出現壓力波動的情況，那為了避免誤差的出現，最高壓力值應盡量小于量程的1/2。
