Murphy轉速小時表 AT / ATH Tachometers
Murphy AT / ATH Tachometers

Murphy AT 和 ATH 系列轉速表采用的電子電路來顯示發(fā)動機轉速。均配有配合 3-3/8 英寸（ 86 毫米）標準儀表盤安裝孔的安裝支架。 270 °掃描的指針使數(shù)據顯示范圍更廣，讀取數(shù)據更輕松。表盤背光適合夜間使用。 ATH 系列轉速表還配有小時計來記錄發(fā)動機的運行時間。

不同型號適用于發(fā)電機、轉速傳感器或者點火裝置的信號輸入。發(fā)電機信號輸入可來自 4,6,8,12,14 或者 16 極發(fā)電機所產生的脈沖 (3-40PPR) 。輸入信號亦可來自摩菲公司生產的 MP 系列轉速傳感器，其適用于帶 50 至 304 齒的飛輪。點火裝置輸入適用于 2-10 缸的火花點火式發(fā)動機。所有型號都適用于正極接地、負極接地或者不接地、隔離的電氣系統(tǒng)，同時可防止極性反接。
