I am looking at monitoring the temperature inside a PLC enclosure to feed back into an HMI, but I haven't used thermocouples/Pt100 before. Heater/fan switching is going to be done by normal thermostats.
I have looked at the price of both and Pt100 sensors are more expensive than than thermocouples. Is there a reason for this, and which one is the preferred solution?
I don't need any great accuracy just to provide a temperature that I can use as an alarm trigger in case of the fan/heater failing and the temp going out of the desired range.
