8. Examples:
8.1 Temperature measurement
A temperature sensor with linear characteristic
(non-linear sensors, e.g. thermocouples have to
be linearised) supplies 0 V at -10 °C and 10 V at
80 °C.
0..10 V is chosen as input range.
Assign -10 as „displayed value at min. input sig-
nal" to the lowest input level (0 V) and 80 as
„displayed value at max. input signal" (10V). The
device is now tuned to the sensor, intermediate
measurement values and their corresponding
display values can be calculated.
Displayed value can be
freely adjusted to the input
value inside the display
range.
8.2 Level measurement
A level sensor with linear characteristic (non-lin-
ear sensors have to be linearised) supplies 19
mA at full tank and 5 mA at empty tank. If the
3
tank is filled up, 10 m
should be displayed and
if the tank is empty 0 m
4..20 mA is chosen as input range.
Assign 0 as „displayed value at min. input sig-
nal" to the lowest input level (5 mA)
and 10 as „displayed value at max. input signal"
(19 mA). The device is now tuned to the sensor,
intermediate measurement values and their cor-
responding display values can be calculated.
