    Calculation of lead lenghts for motor stator RTD's

    The specification sheet for the 469 indicates the following: RTD Sensing current: 5mA Lead Resistance: 25 ohm Max per lead for Pt and Ni type 3 ohm Max per lead for Cu type. I've done the following to get the distance but just want to be sure it's right. I've used Belden cable #1099A which...

    Calculation of lead lenghts for motor stator RTD's

    Yes. I want maximum lead length. I also have some more information. The RTD is 3-wire, the thermocouple is 2-wire. And according to Multilin the 469 only accepts RTD's and not thermocouples.

    Calculation of lead lenghts for motor stator RTD's

    Hi everybody, I'm new at this so please bare with me. I am interested in how to calculate the lead lengths for motor stator RTD's (100 ohm platium) and for motor bearing thermocouples Type K. I have a motor that is approximately 2000 feet from the motor starter and protection relay (Multilin...
