The analog gauges are at-a-glance engine monitoring, foolproof for the user. Incase the PC computer crashes while the engine is running, the user can still see vital engine parameters!! I'm a car guy, so I bought a boost gage
The data acquisition we will be using is LabView through a huge array of Omega transducers.
On the list we have a 0-100 lbs load cell part number LC-304-100 on the omega website. It is in the picture in my first post, used to measure thrust of course. Notice the linear bearing mounted on the underside of the engine.
The fuel flow rate is measured by an FLR-1012 flowmeter again from omega, pressure is omega PX-302 0-50 psi absolute pressure transducer.
Temps are the average K-type thermocouple, SS sheath 1/16" Dia ungrounded. We are finding new ways to snake the thermocouples and pressure transducers into the engine without affecting the engine performance and structure.
Data acquisition and transfer is done by the OMB-DAQ55 omega A/D converter. USB compatible, plug and play, easy! It also has 5 outputs!
All sensors require some power, power sources are accounted for sensor excititation bla bla bla etc...
Sensor outputs are mostly analog 0-5V for pressure and flowmeter or 0-10V for the Load cell (it is dependant on excitation voltage a ratio of 10mV/V output).
Today I spun up the engine on my new 7.5V power source, boy does this thing spin up fast without the current limitations of a 7.2V battery... Woooosh!
