Difference Between PT100 and PT1000

The numerical reference (100 or 1000) pertains to the sensor’s Ohmic value at 0°C. When to use a PT100 and PT1000 A Pt1000 has a much higher resistance level therefore the distorting effect of the resistance in the lead wires will be less significant overall as it contributes to a...
