Standard Optical Pick-up Information
The Optical Pick-Up unit is designed to be temporarily fitted for aircraft testing purposes. It is used to produce a speed reference signal from a rotating component for timing and indexing purposes. OPU’s have an operating range of up to 2 meters and can be used to simplify installation when the use of an MPU is not practical or safe. Helitune OPU’s have been specifically designed for aircraft installations and are ideally suited for use on helicopter tail rotors and high speed transmission shafts.
The Optical Pick-Up unit works by transmitting a beam of infra red light, which is reflected back to the unit by the passing of a target of reflective tape or paint attached to the rotating component. An electrical pulse is produced each time the target comes into view and the red LED indicator illuminates on the OPU body. This signal is used to generate a speed output and a timing reference for balance data, vibration signatures and tracking information.
