Resistance Characteristics Comparison
When evaluating various temperature sensing technologies, it is crucial to understand their resistance characteristics, as they significantly affect performance across diverse applications. Ni1000 sensors and NTC thermistors, such as the 5k, 10k, and 20k types, demonstrate notable differences in their resistance behavior.
Ni1000 sensors maintain a resistance of 1000 ohms at a reference temperature of 0°C, providing a linear and stable response to temperature changes. With a relatively low temperature coefficient of approximately -0.4%/°C, these sensors deliver consistent readings over a wide temperature range.
On the other hand, NTC thermistors exhibit a nonlinear relationship between resistance and temperature. For example, as the temperature increases, the resistance of NTC thermistors can significantly decrease, with temperature coefficients often greater than -4%/°C.
