Electric Swichgage® instruments

The EG21 Series Electric Gage and the EGS21 Series Swichgage instruments take the electric gage to new heights with proven state of the art technology and reliability.

The EGS21 Series Swichgage instrument has all of the features of the EG21 Series Gage plus an adjustable set point PowerHall® 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. Designed for use with electric Swichgage instruments, the EN204 Series Tattletale Annunciator works with other engine components to clearly indicate critical engine operating conditions. The four bright LEDs on the face of the annunciator indicate the cause of an alarm or shut-down condition. Enovation Controls also offers a range of senders designed to be used in conjunction with our EG Series Swichgage Instruments as well as CAN I/O modules.
