5-3. Ventilator Tachometer
1. Tachometer Signal
The tach output can be monitored and conveys rpm information in the form of a square wave (2 block pulses
per revolution). The frequency of this square wave output is proportional to the rotation of the shaft. The tacho
signal can be measured using a frequency meter or pulse counter (12VDC / Pulse signal ~100Hz /
~3,000rpm).
