EG Series:
The 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. Utilizing our proven EG Air Core movement design, the EG21 Series offers technological improvements in overall operation, lighting, accuracy in reading, wiring, and installation. The EG21 Series gives you assurance of highest reliability and service. These rugged gages are environmentally sealed and exceed the rigid SAE J1810 standard for reliability operation in tough off-road and power unit environments. Corrosion-resistant materials are used throughout, making the EG21 highly desirable for marine and other environmentally sensitive applications. Soft, non-glare dial and pointer illumination is provided by a “cold light” LED and when powered the white lettering and clear pointer become soft red. Mirror bａnd eliminates parallax reading error when the pointer and its reflection are aligned. Easy to install, and fits standard 2-1/16 in. (52 mm) opening. The EGS21 Series SWICHGAGE has all of the features of the EG21 Series Gage plus an adjustable set point Power Hall Effect switch output for operating alarms or equipment shutdown. The trip point is adjustable over 90% of the scale and has a set point indicator visible from the gage face. Now you can have both, the ease of electric gage installation and the reliable switching of Murphy's famous SWICHGAGE.
