Hi,
I`m new here and also in "plc world", I`m owner of FX3U clone PLC https://www.lollette.com/le3u-24mt-6ad2da-plc-controller.htm with HMI OP320, because I`m still newbie I have one stupid problem, how to add thermo probe to this PLC and how to get temperature from thermo probe? Best option? Easy option?
Most of thermo sensors are PT100 and they are not with linear resistance change on temperature change and I don`t know how to calculate temperature from analog inputs...
Look like one option is to buy this transmitter:

Other option is to use lm35 but most of them are in transistor housing and I need to use it in wet conditions...
Thanks.
