Principle
A flexible sensing element actuates a microswitch by means of a
piston. The set point is adjusted by means of a compressible spring
installed in opposition.

The value of the dead band is depending on the value of the set point.
This table contains the dead band values for set point adjustment at 10% and 90% of the selected scale. For adjustable dead band the lower value corresponds to
the dead band spring totally released and the higher corresponds to the dead band spring fully tensed. For other set points the dead band value can be calculated
by linear interpolation between the values at 10% and 90%.
