TM202 Precision Dual Tachometer with Bendix Single Magneto Sensors
The TM202 is a precision dual tachometer that provides RPM data accurate to +/- 1RPM. It meets all the requirements of TSOC49b and provides the following functionality:
RPM indication in both analog and digital format for both engines, including support for engines that require a limited RPM range
Independent engine time recording
Trend graph function representing RPM vs. Time for both engines simultaneously
This instrument kit includes two Hall Effect sensors for Bendix type single magnetos. The sensors are mounted in the vent hole (closest to the engine) of the magneto. The instrument will work on all 4, 6 and 8 cylinder aircraft engines.Features:
