TM202 Dual Tachometer Kit - Bendix Dual (3000) Magneto

TM202 Precision Dual Tachometer with Bendix Dual 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 3000 series dual mag/single drive magnetos. The sensors are mounted in the tach drive port of the engine. The instrument will work on all 4, 6 and 8 cylinder aircraft engines.
