Replace your Tachometer with EI’s CGR-30P, and bring glass panel technology to your panel today, without breaking the bank. The CGR-30P is a TSO’d, STC’d Primary Replacement engine instrument. What can it replace? The answer: most of the aircraft’s primary engine functions.
The beauty of the CGR-30P is that YOU get to choose many of the functions the CGR-30P replaces. Designed as a Cluster Gauge Replacement (CGR), the CGR will replace your Tachometer, Manifold Pressure, Fuel Flow Totalizer, EGT/CHT Bar Graph Analyzer, and more!
The CGR is divided into three separate screens. The three screens are the Main Screen, Secondary Screen, and the Fuel Management Screen.
Both the CGR-30P and CGR-30C measure AMPS by using an external shunt. Depending on where the shunt is located will determine what you are measuring, and it’s possible to measure more than one shunt. For example; if you put a shunt between the battery and bus you will measure current draw and charge current from the battery. If you put a shunt between the alternator and the bus you will see total alternator output. It is possible to do both on either instrument.
