如何選擇壓力開關的調節范圍
選擇壓力開關調節范圍時，要注意這個范圍一定要可以起到保護壓力開關的作用，該范圍的選擇要考慮到壓力開關的設定值。下面小編給大家介紹下選擇壓力開關調節范圍的原則。
由于壓力開關的動作精度與設置的設定點的高度有一定聯系，一般情況下，當設定值超過調節范圍上限的30%時，那么該壓力開關的動作精度就會更加優越，反之，當設定值小于調節范圍上限的30%時，那么該壓力開關的動作精度就會比較差，所以調節時，為了達到更高的精度，壓力開關的設定值應大于調節范圍上限的30%，并盡量接近調節范圍的上限。
補充：壓力開關的最大調節范圍與最大壓力不同，設定的最大壓力都需要有足夠的空間來滿足用戶的實際工作壓力的要求，要比最大調節范圍還要更大。
