5.1 Analog Input Channel
The Analog Input Channel collects and processes the signals of
the most common types of sensors. A large number of stan-
dardised sensors is already stored in the COMBILOG’s internal
sensor data base. Further sensors can be added by the user.
Following measuring principles are provided:
Voltage measurement
Current measurement
Resistance measurement
Temperature measurement with thermocouples
For
each
of
these
principles
the
datalogger
COMBILOG 1020
of-
fers several types of measurement. For voltage measurement the
types of measurement
single-ended
and
differential
can be used.
Currents up to 25 mA are directly measured by the datalogger.
Current measurements of more than 25 mA can be carried out by
measuring voltage drop at an external shunt. Resistance measur-
ings can be carried out in 2-, 3- and 4-wire technique.
