壓力傳感器與壓力開關的聯系
壓力傳感器是組成壓力開關測量部分的重要元件，它可直接將壓力轉換成測量電流或電壓，進而通過電路調節信號來檢測和傳輸壓力。
壓力傳感器測量的信息是否正確直接影響了壓力開關的測量精度，因此，壓力傳感器是所有壓力開關的核心組成部分。當用戶在選購壓力開關時，需要考慮到壓力傳感器的各項指標，如工作環境，測量介質，測量壓力大小等，這些不僅僅要適合壓力開關，還要適合壓力傳感器；使用壓力開關時，不僅要監控整個壓力開關，還需針對壓力開關內部的壓力傳感器進行監控，防止壓力傳感器出現故障引起突發事故；維護壓力開關時，也要重點維護壓力傳感器，定期清洗壓力傳感器，定期檢測壓力傳感器的性能。
由于壓力傳感器的測量范圍較寬，不僅僅適用在壓力開關中，也適用于各種壓力測量場合，是精密儀器儀表行業中不可缺少的元件之一。
