Hi,
On a diesel engine, we want to monitor pre-turbo exhaust gas temp using a K-type thermocouple. We already have a MC050 controller on the machine.
Do you have suggestion of a rugged/automotive thermocouple amplifier that has a decent output that can be fed in an AnIn pin of the MC050 controller?
Thanks in advance!

I don't have an amplifier that I can suggest, but perhaps you can get by without one. K-type thermocouples will generate a signal of about 0 - 60 mV. Some of the multifunction inputs allow you to change the range to '2' which is 0 - 0.3675 Volt. I don't see an indication that this has lower resolution for that range, so I'm guessing you get the full 12-bit resolution. If that's the case - I'd verify with Helpdesk - then you can get by without an amplifier. You'd get a resolution of about 0.09 mV.
