Abstract
An online sensor for monitoring chemical contaminations in hydraulic fluids, having a receiving device for the fluid to be monitored, the device having observations windows disposed on two opposite sides, is characterized in that the online sensor has an IR emitter and an IR detector comprising at least two, preferably four detector fields for IR spectroscopy, wherein the fields are disposed opposite of each other on both observations windows. This provides a sensor that is capable of detecting the maintenance-relevant parameters of hydraulic fluids based on phosphate esters online, which is to say without having to withdraw the same from the airplane's hydraulic system and remove the same as a sample.
