转速表

Murphy转速小时表 AT / ATH Tachometers
Murphy AT / ATH Tachometers

Murphy AT 和 ATH 系列转速表采用*的电子电路来显示发动机转速。均配有配合 3-3/8 英寸（ 86 毫米）标准仪表盘安装孔的安装支架。 270 °扫描的指针使数据显示范围更广，读取数据更轻松。表盘背光适合夜间使用。 ATH 系列转速表还配有小时计来记录发动机的运行时间。

不同型号适用于发电机、转速传感器或者点火装置的信号输入。发电机信号输入可来自 4,6,8,12,14 或者 16 极发电机所产生的脉冲 (3-40PPR) 。输入信号亦可来自摩菲公司生产的 MP 系列转速传感器，其适用于带 50 至 304 齿的飞轮。点火装置输入适用于 2-10 缸的火花点火式发动机。所有型号都适用于正极接地、负极接地或者不接地、隔离的电气系统，同时可防止极性反接。
