Murphy轉(zhuǎn)速小時(shí)表 AT / ATH Tachometers
Murphy AT / ATH Tachometers

Murphy AT 和 ATH 系列轉(zhuǎn)速表采用*的電子電路來顯示發(fā)動(dòng)機(jī)轉(zhuǎn)速。均配有配合 3-3/8 英寸（ 86 毫米）標(biāo)準(zhǔn)儀表盤安裝孔的安裝支架。 270 °掃描的指針使數(shù)據(jù)顯示范圍更廣，讀取數(shù)據(jù)更輕松。表盤背光適合夜間使用。 ATH 系列轉(zhuǎn)速表還配有小時(shí)計(jì)來記錄發(fā)動(dòng)機(jī)的運(yùn)行時(shí)間。

不同型號(hào)適用于發(fā)電機(jī)、轉(zhuǎn)速傳感器或者點(diǎn)火裝置的信號(hào)輸入。發(fā)電機(jī)信號(hào)輸入可來自 4,6,8,12,14 或者 16 極發(fā)電機(jī)所產(chǎn)生的脈沖 (3-40PPR) 。輸入信號(hào)亦可來自摩菲公司生產(chǎn)的 MP 系列轉(zhuǎn)速傳感器，其適用于帶 50 至 304 齒的飛輪。點(diǎn)火裝置輸入適用于 2-10 缸的火花點(diǎn)火式發(fā)動(dòng)機(jī)。所有型號(hào)都適用于正極接地、負(fù)極接地或者不接地、隔離的電氣系統(tǒng)，同時(shí)可防止極性反接。
