TM200 Precision Tachometer with Bendix Single Magneto Sensor
The TM200 is a precision 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, including support for engines that require a limited RPM range
- Engine time
- Trend graph function representing RPM vs. Time
This instrument kit includes the Hall Effect sensor for Bendix type single magnetos. The sensor is 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.
