based on limit setting at T
If the ambient temperature at the switch head and / or the capillary deviates
from the +22°C calibration ambient temperature, there will be a switching
point displacement.
Higher ambient temperature
Lower temperature

0.35 °C per °C
If the operating temperature differs appreciably from the +22°C calibration
ambient temperature, it is possible to allow for this during calibration (at extra
charge).
