Ni1000 6180

rtd_sensor.ni1000 represents the former DIN 43760 / Nickel ND nickel characteristic with 1000 Ω at 0 °C. It is not a generic model for every sensor marketed as “Ni1000.”

Supported characteristic range: -60 °C to 250 °C.

Its normalized forward relationship is represented by the documented polynomial:

R(T) / R0 = 1 + 5.485e-3 T + 6.650e-6 T²
              + 2.805e-11 T⁴ - 2.000e-17 T⁶

Quick use

from rtd_sensor import ni1000

resistance_ohms = ni1000.celsius_to_resistance(100.0)
temperature_c = ni1000.resistance_to_celsius(resistance_ohms)

Why the explicit name matters

Different Ni1000 families use different resistance-temperature curves. In particular, Ni1000 TK5000 is a distinct characteristic and must not be substituted simply because both models are 1000 Ω at 0 °C.

Physical product limits

A manufacturer may specify a narrower range for a packaged sensor than the mathematical characteristic represented here. Apply those product-specific limits separately.
