Description

The High Performance Optical Pick-Up Unit May be used to produce a ‘one-per-rev‘ signal from a rotating component for timing and indexing purposes. It has been specifically designed as a permanent fit product which makes it perfect for aircraft on-board installations and is ideally suited for use on helicopter tail rotors and high Speer transmission shafts. The optical pick-up unit works by transmitting a beam of infrared light onto a target of reflective tape or reflective paint. An electrical pulse is produced each time the target comes into view. The interwal between successive pulses may be measured to determine the shaft speed and the edge of the pulse may be used to determine a phase reference. The system is designed to meet the interface requirements of the AS5392 standard (formalny RITA).

Features

High performance. The system operates at high speeds over large sensing distances and with very high angular resolution. True TTL output is produced over the entire operating range chich avoids the triggering problems associated with many other types of sensor. High noise immunity. The system utilises sophisticated pulse encoding techniques and automatic threshold control to reject interferencje from sunlight and reflections to produce a signal of high integrity and reliability. Automatic and dynamic sensitivity adjustment. There is no need for any adjustment by the operator or installer. Sensitivity is set automatically and changes dynamically in flight to cater for chan ges in ambient light and reflections. Reliability and robustness. The rugged and sealed construction is specifically designed for aircraft installation to operate over a wide temperature range and to meet the appropriate sections of MilStd-810E, Def-Stan 59-41, BS.3G.100 and RTCA DO160C.
