如何確定壓力開關的量程
量程是確定一款壓力開關的最重要參數之一，想要知道要選多大量程的壓力開關，就要事先知道日后壓力開關測量的是哪種壓力，壓力大小是多少。今天小編就教您到底該如何選擇壓力開關的量程。
量程范圍是指壓力的范圍，所以務必要先知道被測壓力的大小，然后根據被測壓力來決定所選量程范圍，并且考慮到可能出現的過壓過載情況，決定量程時，還要留出一定空間，因此，在選擇量程時，最好選擇比最大壓力還大1-2倍的范圍。針對其他特殊情況，如：測量的是脈沖壓力，則應選擇比最大壓力還大2/3的量程。
量程選擇的正確與否直接決定了日后壓力開關的精度等級高不高，并且要保證日后正常工作時，不能有超量程工作的情況。
