1048 or 1018

Postby te5ter » Fri Jan 17, 2014 6:45 am

I need to read to 4 temperature probes. Since the 1018 has 8 analog inputs can't I just use it alone? Other than preserving analog inputs are there any other reasons to use the 1048?

Thanks.

Thermocouples have a very low voltage output. The analog inputs on the 1018 aren't really sensitive enough to measure them accurately. The 1048 on the other hand has a higher precision ADC which is well suited to measuring small voltages.
