ROTOR SPEED SENSOR

TEMA Sensor Rotor Speed is a magnetic pick-up (alternating voltage generator).
It consists of three indipendent and insulated coils wrapped on an unique magnetic core included in a stainless steel case which provides an hermetic sealing and EMI shield against the external and internal environment.
The purposes of this equipment is to provide an output for the indication of main rotor speed, provide an output for the equipment/systems as ECU, AS, etc. and provide an output as tachometer signal for vibration signals processing purpose (e.g. time averaging).
