Measured variable Main variable
Adjoining variable Main variable designates
the actual measured
parameter of the sensor
(e.g. pH, oxygen, etc.).
Adjoining variable
designates an additional
measured parameter
(e.g. temperature).
Attenuation 0 ... 40 mA/s Speed of change of the
output current (mA/s) in
the case of erratic
changes of the input sig-
nal.
