    計數器(又稱「脈衝計」、「電子計數器」)是一種用來記錄和顯示頻率的裝置,簡單來說,就是能夠準確計算測試對象產生變化的次數,因此被廣泛應用在自動化生產、機械、醫療、運輸等眾多產業,以確保機器運作能夠保持穩定。

    RS歐時提供一系列的計數器類型,包括數位(電子)計數器小時計數器機械式計數器等,能滿足各種工業和商業項目上對精準測試的嚴格要求。我們提供多種優質品牌可供選擇,包括BaumerOmronRed LionKübler ,當然不少得我們的自家品牌 RS PRO

    計數器的工作原理

    數位(電子)計數器和機械式計數器的運作原理相似,它們有一個專門的電路,當收到一個輸入訊號(如脈衝)時便會記錄下來,以記錄和顯示測試對象所出現變化的頻率。脈衝計數器會與時鐘同步工作,亦即它會根據時間脈衝進行計數;而電子計數器內部設設有一個序向邏輯電路,以接收時鐘輸入信號作為計算原理。在香港,這些計數器被廣泛應用在工業環境,以測量以下指標:

    • 長度
    • 脈衝
    • 經過時間
    • 位置指示
    • 開關和控制

    計數器的種類

    數位(電子)計數器

    數位計數器設有電子屏幕可顯示測試數據,它的內部設有觸發器,當數值達到一個預先設定好的值時,觸發器便會啟動,從一個位置切換到下一個位置;當數值達到另一個預設值時,觸發器又會再次切換回來,以確保流可以順利流動。

    非同步(脈衝)計數器

    計數器由多個觸發器組成,可計算輸入的脈衝信號數量。輸出是採用二進制數值,代表接收到的脈衝數。

    同步計數器

    同步計數器的時脈頻率會同時傳送到每個觸發器上,電路計算的結果會更加準確穩定,特別適合於高速操作。

    十進制計數器

    專門用於計算十進制數字、而不是二進制。

    環形計數器

    觸發器排列成一個環形結構,最後一個觸發器輸出的數據會反饋到第一個觸發器中。

    機械計數器

    機械式計數器由機械元件構建,通常由安裝在軸上的一系列圓盤組成,圓盤邊緣標有 0 到 9 的數字。

    小時計數器

    小時計數器主要用來記錄設備的運行時間,通常以小時和1/10小時的形式顯示。

    計數器的用途

    工業計數器的用途廣泛,在香港的眾多產業也不難看見他們的身影,例如:

    • 自動化
    • 機械製造
    • 能源管理
    • 醫療
    • 運輸
