T
his unit consists of a

isolating system with metallic process diaphragm
.
A
special fea

ture of this isolating system is that the temperature in
fl

directly compensated mechanically
.
T
he process pressure causes via the respective diaphragm a
change in an elec

his change
is converted into a corresponding output signal
