[RE-wrenches] Outdoor rated flexible metal cable

[Peter Parrish]

I recently had the opportunity to visit a City of Los Angeles Remote
Automated Weather Station (RAWS). See
http://cdec.water.ca.gov/cgi-progs/queryF?s=mtw&d=now&span=24hours

I noticed that the system was wired using a flexible metal cable (1/2"). It
had a continuous outer metallic covering that looked to be aluminum. I asked
my host about the cable and he said that he hadn't been involved in the
installation and didn't know much about conduit/cable/wire. The conditions
are certainly "damp" i.e. outdoors, but I don't know about "wet". The cable
runs were completely exposed to the weather.

The cable carried low voltage "data" and "power". I am pretty sure it didn't
carry 120/240Vac, but again my host didn't know.

Does any one know what this cable might be?

If you would like a photo, I could send one off-line.
