probe material
Min. bending
radius of
capillary 5 mm
Switching point

Mean ambient
temperature
effect in % of scale span, referred to limit.
A deviation of the ambient temperature at the housing and / or the capillary
from the calibrated ambient temperature +22°C will result in a switching point
displacement:
higher ambient temperature = lower switching point
lower ambient temperature = higher switching point
