    Can anyone tell me what type/standard do PTC thermistors follow commonly
    found in motors in the UK.
    Also, is there a calculator available online or for download for these
    thermistors.
    I have a submersible pump and the resistance is measured at 148 Ohms. I
    assume there are three thermistors in the motor connected in series.
    I would like to know the winding temperature from measuring thermistor
    resistance, not just for this pump, but for all motors with thermistors at
    our sites.
    TIA
