This still does not answer your question, and I am by far not an expert, but I just ordered 15 of these: 1182-1011-ND
from digikey. I have only used them for some bench testing and I won't have results for a few weeks/months from the intended project. From my reading though, the above referenced...
Ok guys, a lot of good input and suggestions so thanks a bunch for that.
I really do need a thermocouple. It is an exhaust gas temp (EGT) sensor. I actually don't know the exact EGT value, its just being converted to an analog voltage for either the end user to have as a relative tuning...
So shielding would probably help, but the only thing I know about shielding is what I have observed in cat6 cable (foil wrapped around the wires with a drain wire going to ground). How would I implement RF shielding on a small opamp circuit? This probably sounds really naive, but the only thing...
I have a temperature probe that I amplify with an OP amp and the circuit has to sit next to a video transmitter operating at 1280 MHz outputting ~ 800 mW of power.
I can get the circuit about a meter from the transmitter if I absolutely have to but it is going to be in somewhat close...
If I could change my setup to substitute the direct coupled AC motor for an induction driven AC motor that operates at a much higher RPM, say 40K, which would bring my rectified frequency to 4kHz; would that gain me anything? It looks like I would need much less filtering capacitance at that...
Ugh – I forgot that tiny little fact the motor RPM (for my motor) is frequency dependent…
Batteries in parallel: I will work on managing the batteries later – I think/hope that will be much simpler.
Thanks a ton for providing those weight figures – the transformer seemed so promising and I...
I am building an on-board generator for a small aircraft (AUW = ~ 10kg). The fuel motor is rated at 1.8 kW and it directly drives a 3 phase AC motor. The rpm will be regulated at roughly 8k so I think the frequency of the AC output will be around 133 Hz. The AC motor produces 1 volt per 260 RPM...
