Hi If it is ok I will use this topic to ask some help with my pt100 problem. I would like to know is there any ways to correct/compensate the "loop impedance" caused by a long cabling? I have use -50 to +200 Pt100 sensors connected to RTD module. Because of the long distances there is several ohms impedance that I would need to compensate or get rid of somehow. Double wiring or bigger diameters probably wont get it all away so it would have to be done through program. I am measuring temperatures that go below 0 degr. So changing to pt1000 wont work either. But I'm surprised if there is no way in LOGO! to set a correction to pt100 value. ------------------------------------------------------------------------------------------ |
