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-linear sen sors ha ve to be li nea ri sed)
supplies 19 mA at full tank and 5 mA at empty
tank. If the tank is filled up, 10 m
displayed and if the tank is empty 0 m
be displayed. 4...20 mA is chosen as input
range.
Assign 0 as „displayed value at min. input sig-
nal" to the lo west input level (5 mA) and 10 as
„displayed value at max. input signal" (19 mA).
The device is now tu ned to the sensor, inter-
mediate measurement values and their corre-
sponding display values can be calculated.
8.3 Drawn quantity
Instead of the level, the drawn quantity should
be displayed.
Again 4...20 mA is chosen as input range.
Assign 10 as „displayed value at min. input
signal" to the lo west input level (5 mA) and 0
as „displayed value at max. input signal"
(19 mA).
8.4 Level measurement with limited
display range
A third example is level measurement with
limited display range, that means a tank with
10 m
its level should not decrease below 1 m
values > 8 m
at values < 1 m
4...20 mA is chosen as input range.
Assign 0 as „displayed value at min. input
signal" to the lo west input level and 10 as
„displayed va lue at max. input signal"to the
highest input level.
Additionally, program for menu item „min. input
signal", the value of which cor re sponds to the
