SES Solid State Data Recorder - Engine Monitoring Unit

The S3DR product family is a low cost, high performance, rugged solution to the processing and data recording needs of an environmentally challenging embedded system, such as those found in aerospace, defence, naval, vehicle and safety-related or high performance industrial applications.

S3DR-EMU (Engine Monitoring Unit) is a specialisation of the more generic product family providing a dedicated data acquisition and recording solution certified by the FAA for use with the Rolls-Royce Corporation Model 250-C300 (RR300) gas turbine engine.

The S3DR-EMU records power turbine and gas generator shaft speeds, engine torque and gas temperature from engine sensors and also its own internal temperature. The unit stores additional parameters such as number of engine starts and accumulated engine run time. It also detects excursions of recorded parameters outside programmable limits and records data during such events, at a higher than normal sample rate. Recording duration is in excess of 2,000 hours.

The S3DR-EMU provides a high speed USB II data download interface, to allow data to be extracted from the unit using SES developed Data Download Software.

A key feature of the S3DR-EMU is the electrical isolation offered by its input circuit design. The software and hardware design architecture is scaleable to allow the number of recorded interfaces to be expanded, if required.
