OT: Temperature and voltage monitoring

[Tom Hudson]

I apologize for the OT nature of this, but knowing how many excellent 
engineers are on this list, I thought I'd take a shot...

I need to monitor temperature and voltage of 24 batteries in 
more-or-less real time (say, one sample every 10 seconds).  The 
batteries are connected in series, so I need to have isolation on the 
voltage sensors.  Ideally, I'd want to have the sensor output available 
via RS-232 at some decent rate (say, 9600 baud).  Temperature range 
would be 0-100C, voltage from 0-16VDC.  This is for the batteries on my 
electric truck, BTW.

Does anyone know of a reasonably-priced, off-the-shelf unit that can do 
this?  Email me privately if you'd like, or on the list if you don't 
think this is too off-topic (you can just pretend I'm going to be 
reading the data with my Atari ST).

Thanks!
