壓力開關的精度說明
精度等級是判斷一個壓力開關好壞的重要性能指標，是決定能否穩(wěn)定工作的重要因素，也是關系到整個測量系統(tǒng)精度的重要環(huán)節(jié)。
壓力開關的精度等級是否高，主要在于內部的壓力檢測元件—壓力傳感器。壓力傳感器的精度越高，壓力開關的精度也會越高，但是價格也會相應的更高，所以用戶在選擇壓力開關時，只要根據自身情況來選擇不同精度等級的壓力開關，只要滿足整個測量系統(tǒng)的精度要求即可。如果是測量目的是定性分析的，最好是選擇重復精度高的壓力開關；如果是為了定量分析，那測量結果就必須是精確的，就需選用精度等級能滿足要求的壓力開關。如果是特殊的工作環(huán)境，需要壓力開關有特殊的精度等級，可以將要求提供給廠家，讓廠家依據要求定制。
壓力開關的精度等級會受到多數因素的影響，具體可閱讀：哪些因素會影響壓力開關的精度。
