Sounds like you have a System [1] with sensors (possibly sensing devices)
as sub systems [2].

Note that a sensor is "any entity that can follow a sensing method" [3] and
can include a lab technician who follows a protocol to measure a property
while a sensing device is an instrument. A sensing device is a sensor,
while a sensor may be a physical object other than a device.

I think I would model serial numbers for systems, which will also work for
sensing devices.

Looks like a sensible approach, especially if you want the first ontology
with your classes to be reusable.
