I am attaching my Pi 3 to two delicate sensors via USB. My question is, if i was to take the power cords from the sensors and attach them to a male USB cord. The problem is, anything more than 5.5V will fry the sensors permanently and each one costs around $2000.00.

I've looked at different Data sheets for the Pi-3 and have not found the information I am looking for.

Any help would be greatly appreciated.

~6W — You can draw 1.2A

The voltage is derived from the power you connect to the Pi, which should be 5±0.25V. The Pi does have a diode to limit over voltage, but this is only intended to limit transients.

So the answer to your question depends on what you supply to the Pi.

See Raspberry Pi Power Limitations for further detail and description of the Pi circuitry.

I believe the Raspberry Pi does not regulate the voltage fed to the USB. If your Pi is receiving 5.5V from its power supply then that voltage will be output to your USB will be 5.5v, you could test this using a multimeter.
