Calibration
In order to achieve an accuracy better than ±1 K of the temperature controlled, the accuracy of the sensor and the connecting cables must be better than ±0.6 K.
All sensors have a measuring accuracy below ±0.45 K within the HACCP defined temperature range of -30 °C to +20 °C. This is why it is essential that the cable resistance does not exceed 0.15 K.
The cable resistance expressed in Kelvin can be calculated by using the formula below:
ρ x L
R = -------------
3.85 x q
R = Cable resistance expressed in Kelvin
ρ = Specific resistance of the material [Ω/m/mm²] L = The length of the wire [in m there and back] q = Cross-section of the wire [mm2]
Example: ρ = 0.018
L = 10 m x 2 = 20 m q = 0.75 mm2
R = |
-----------------0.018 x 20 |
= 0.12 K |
