Murphy EG和EGS系列电动式仪表更精确、更耐用、更先进
MURPHY EG / EGS Series Electric Gauges

Murphy EG21系列电动仪表和EGS21系列电动继电式仪表以先进的技术和可靠的性能把工程机械专用仪表推向了一个新的高潮。Murphy's EG21 Series Electric Gage and the EGS21 Series Swichgage take the electric gage to new heights with proven state of the art technology and reliability。

EGS21系列电动继电式仪表在拥有EG21所有功能的基础上，还增加了一套可调基点的“霍尔效应”开关输出，可触发报警或关闭机器。触发值可在刻度的90%范围内进行调节，并可在仪表刻度盘上显示。你不但拥有了电动式仪表安装的简便，还享受到了摩菲公司著名的继电式仪表的可靠性。
