Speed sensor input output?
Answer:
Input : 24v DC
Output : 5-18v pulse which frequency is proportional to turbine rotor speed (number of teeth in 360 deg varies with different turbine). Speed sensor having sensor, amplifier and controller. Sensor works basses on eddy current principle.
F = (#teeth* RPM)/ 60
Example(120 teeth and 3000 RPM)
F= 6000 HZ
