Principle
A vapour filled sensing element actuates a microswitch by means of
a lever. The set point and the dead band are set by springs mounted
in opposition

For max. ambient temperature according to temperature classes T5 and T6 refer to technical data on page 1.
The installation must be made in an intrinsically safe circuit whose certified electrical safety parameters do not exceed any of the values Umax,
Imax and Pmax given in the electrical data on page 1.

All necessary measures must be taken by the user, to avoid the calorific transfer from the fluid to the apparatus head increasing the head's
temperature to such that it reaches the self-ignition temperature of the gas in which it is used.

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%.
