WARNING!
Under the following operating conditions, the safety function of the
instrument is not guaranteed:
■

2.3.8 Safety function

The safety function of the instrument is that, on falling differential pressure, the
respective switch(es) will open. The changeover contacts should always be used
so that the circuit opens on falling differential pressure (observe the closed-circuit
principle).
2.3.9 Accuracy of the safe switching function
The following information on the total safety accuracy contains:
Basic accuracy (measuring deviation, linearisation error)
■
Influence of the ambient temperature in the range -10 °C ... +70 °C
■
Influence of up to 259,835 load cycles
■
The total safety accuracy is -12 % ... +8 % of the measuring span for the differen-
tial pressure.
