Hi there,
The RTD Pt100 is used to monitor the temperature of devices, and the output of this RTD (Ohms) is sent to the control room which is far away from these devices with the range (350 to 1250 meters), is it ok to send ohms via such long cables? or is it better to use a Temperature Transmitter to convert this Ohms and send them as 0-10 V or 4-20 mA ? And which is better for this purpose: sending as 0-10 V or 4-20 mA and why ? Thanks.
